This is how I found the Clark Belt prior to mounting my satellite with a little help from the USGS. I had to make sure no trees were gonna be in the way.
Great idea! Mapquest used to have a "free" similar function, I used to check every installation address before I rolled my truck just so that I knew what I was going to be up against. Thanks for the picture!
I know you can do this alot easier with one of those map programs that comes with the Garmin GPS units, MapUSA or MapTopo I think. It has the compass and everything.
