Exactly my point: Life in LA really can be a MICRO experience, such as is the MICRO-Climate here. And you were NOT living in a desert. The desserts--as in REAL, PROPER desserts, not facsimiles--are on the other side of the mountains such as the Antelope Valley, the Victor Valley and San Bernardino and Riverside counties, and those places really have climate that is out of another planet.You were living in what is classified Mediterranean Climate with Desserts classified as getting less than 10" of rain per year with the LA area in general getting and average of 14" per year. I believe Antarctica and the Arctic are also classified as "desserts." We just don't get a lot of rainfall below the mountains, but the mountains average is about 40" per year, hence the largest, most complex flood control system in the world. It is a wonder it does not flood here like it should, but that is not by accident, and sometimes still a challenge. Devastating floods up to the 1930's taught is big lessons, the hard way.
LA is no Las Vegas or Phoenix or even some Texas cites that are truly dessert climate and conditions. We just get NONE of that here, and people from those places think we are crazy and don't know what HOT (and HUMID) really is. In Santa Monica people think 78 is "HOT". Outsiders who come love how "cool" and "comfortable" it is compared to the hell they used to live, and that includes just about every other part of the country except for the Pacific Northwest. Outside the true dessert areas and the SFV & SGV Valleys and Long Beach, 80 degrees is warm and uncomfortable for us and getting to 85 degrees is really too HOT for most of us, we can't really handle it well, and heaven forbid the humidity is over 30%.
Maybe 10+ years ago we had Las Vegas-Phoenix weather for about 2 weeks, with no cooling at night, a saving grace in the summer here (a wild FREAK event), and we had countless 20+ year old transformers in neighborhoods blowing up and causing numerous small scale power outages every day with people out of power for days before local transformers were replaced, yet Vegas and Phoenix handle that weather with "no sweat," but it was major event that almost catastrophic!
The vast majority of us are traveling more than a few miles can't really escape the tyranny of the terrain, and I am surprised that you thought everyone could get the RF towers at Mt. Wilson and Mt. Harvard. Way, way, way more people than even I thought are living in the shadow of a hill or mountain that has NO HOPE of ever getting any RF from either Mt. Wilson or Mt. Harvard. Heck, I am a few miles away from a First Effect Hill that challenges my reception of some OTA TV stations from Mt. Wilson, and Mt. Harvard, and you can't even SEE the hill from the ground that casts a shadow for me, although I can get about 85% of the channels (something like about 135-148 Channels, but still missing like 20-30 more from Mt. Wilson and Harvard not counting a few with Xmtrs NOT on the SGV Mts but on other peaks not LOS of Wilson & Harvard), but those poor buggers just a few blocks north of me are in real trouble and even more houses beyond are getting NOTHING, and this is the case all over--IF you are in the shadow, but not everyone is, but more than I would have ever thought, especially RELIABLE signals from the SG mountains.
It may be that some people just don't get around much, nor have they lived in various parts of LA and Orange County to experience for themselves. I have, and hills and mountains are everywhere and hard to avoid for a great many people.
