We have some really cool ones out here, but they are so far apart, it would take forever to explore them all. Quite a few are out in the desert, I've been to a number of them years ago. Nothing there for the most part, but gravel and ocassionally a foundation. The site's pictures don't give the veiwer the real feel of desolation of those places.
Up in the north state, the surviving ones (that have escaped development) still have buildings and even the occasional boneyard. Now those would be worth a little exploration photographing.
