Thanks, it was great to get back out there, but I'd love to have a few months like you did. I'll have to look for Mark's cave photos. Moffett Field access was kind of an accident/mistake, and I don't think I'd be able to get it again. They are pretty sticky about the NASA side of the base, but I don't think I was sneaking up on anybody with my view camera. They had to take the skin off the big hangar, but Google has offered to replace it if NASA will let them keep their fleet of jets in it. Only in Silicon Valley...
