In So Cal, flying fields are all but gone. You can set up a field in the most gawdawful location, some developer will build a golf course next to it, or some of those 40 room houses on postage stamp lots and you have to move again. Happened to my club field. After the second move, we ended up in the bottom of the flood control channel. Absolutely a crummy place to fly as there is a raised highway on one end, trees on the other end (not allowed to prune those!!!) and boulders and swamp all around but at the parking lot. You either land on the runway or kiss your plane goodbye.
Well, this winter mother nature stepped in where the developers could not and buried the field under 6 feet of mud, rocks, sand and debris. Now the county wont let us bulldoze it back out because of nature concerns even tho there is no nature left.
Oh, those houses in the background of this picture are sitting on our last field...
