I've also been attending Dayton since 1992 only missing a couple years. It used to be held in April but the weather was so hit and miss. One year it would be great, the next it could be 100 degrees, the next non-stop rain with the flea market submerged in a foot of water, the next with snow, wind and icicles sideways off the Mendelson's tent. The weather in May has been a lot better in general.
Hamvention completely dwarfs any other hamfest in the hemisphere. Even amidst the recession, hamvention attracted 22,000 people last year. This is down from a few years ago when they've topped 30,000 but is still encouraging that even with the economy, eBay and the internet in general, and people saying ham radio is a dying hobby that 22,000 people come to Hamvention. There's something there for anyone with an inclination towards computers or electronics, not just radio. 15 years ago or so they tried separating the computer stuff from the electronics by setting up a "computer show" across the street at an old car dealership. That idea didn't last long. Inside there are many exhibitors showing off new equipment letting you try it hands on, something that many of us don't get the opportunity to do as we often buy things sight unseen online. Every manufacturer has a display and every store has a booth you can buy from with hamvention exclusive discounts. The flea market takes up a giant portion of Hara Arena's parking lot. You often beat any price you find online, even on eBay, and you are free to negotiate. I've seen truck loads full of surplus electronics, pallets and boxes full of stuff marked $1 each with people digging through them like crazy. Circus tents filled with everything imaginable. Computer parts, electronics parts, tubes, law enforcement equipment, lock pick sets, you name it. You could walk through it all 3 days and see something different every time.
Some people go Saturday only but there's good things about all 3 days. Friday at open it's good to hit the flea market first thing. The ridiculously low priced stuff will still be there. Don't think about it, just get it before someone else does. Sunday people are getting ready to leave and will mark down things just to get rid of them. The wife said they couldn't bring anything back so they'll be priced to move. In fact, a lot of things get left in the lot marked as free, please take. You'll see the roving scavengers taking trailers full of free stuff. Plus all the hourly prizes that aren't claimed get redrawn inside the arena and they keep drawing until someone present wins so your odds are pretty good if you stay for this. A lot of these hourly door prizes are worth hundreds of dollars. The main prizes you don't have to be present to win. Most require a 1099 tax form because of their value. The grand prize has been worth $12,000 in the past.
There are a ton of forums that are veiry informative. There's always a couple that interest me and I attend each year. I might check out the high altitude balloon launch forum. They're going to attempt to launch one on Friday. There's also many off-site activities and dinners. I think the biggest are Contest University and the Contest Dinner. The Crowne Plaza in general has a lot of after hamvention hours activities, pizza and beverages.
FTA and ham radio are two hobbies that often appeal to similar type individuals. It's been great to see Sadoun at hamvention the last few years. I love seeing long time hams drop by the FTA displays having no clue about what FTA is and end up picking up a system. Hopefully hamvention can similarly draw in people from other hobbies to enjoy the show and maybe see what ham radio is about in the process. I'll be stopping by Sadoun's booth again this year and probably buy something like I always end up doing!
Don't forget there are other things to do in the Dayton area like the Wright-Patterson Air Force Museum which is free and well worth the visit.
Tickets are $20 and you can get them on
Dayton Hamvention 2010 - Amateur Radio Clubs Worldwide: The Lifeline in advance. Years ago they had shuttle buses go to the area hotels. Some hotels still offer this (Holiday Inn Fairborn). What Hamvention has been doing officially the last few years is allow free parking at the nearby Salem Mall and then you buy a bus ticket ($8 for all weekend this year) and the bus will take you down the road to the arena. They run very frequently. Many also park here overnight with RVs and the sort. As others have mentioned you can park in the fields across the street from the arena for about $8 a day, but these can be a disaster if the fields are muddy. I've seen towing companies make a killing in years past! The $8 weekend bus ticket works on the entire Dayton RTA system. Their Northwest Hub is right next to the Salem Mall. I've never tried it but it looks like the hotels at I-70 and US-48 have free airport shuttles and there's an RTA bus (Bus 24) that goes from the Meijer at that exit to the NW Hub in 7 minutes so it's possible perhaps with some walking to get from the airport to your hotel and hamvention the whole weekend for $8.
Also, if you live within 200 miles or so, check with your local amateur radio club. Clubs often get a bunch of people together for a one day bus trip to Dayton on that Saturday. I know there's ones from Terre Haute, Akron, Kalamazoo and more. These clubs will welcome anyone, amateur operator or not and will be happy to fill another seat on these buses they charter. This is great for those who don't care to drive and worry about hotels and parking.
The tip about bringing cash is a very good one! There is an ATM at the arena but it ALWAYS runs out very early on. The commercial vendors do take cards though. There is handicapped parking available. Scooter rental is available. Check out the hamvention page for more info
