The "Roman Pool" at Hearst Castle. No tripod or flash allowed!

Wow. When I saw the thumbnail, I thought "Hey, that looks like the indoor pool at Hearst Castle, but it can't be, because they don't allow tripods in there."

Nice steady shot, I've always been too afraid to try it, but I've never had such a fast lens, either. I've always wanted to try a polarizing filter in there, too, to see into the pool, but we're talking about REAL SLOW shutter speeds, then.
