Jeff:
I went to San Miguel mountain two days before the recent fires started in So.Cal. I found most of the mountain access blocked by a gate with plenty of "No
Tresspassing" signs. The flat areas are now taken over by emu, ostrich or sheep farms and expensive housing. If the housing foundations mentioned in that news article were there, my guess is they are now under modern structures--or at least on private properties. Current aerials of the area show no signs of the past--at least to my old eyes--but the trip there and a couple of cold ones with the locals to learn more made the day a great adventure.
