Those are a lot of great photos, Ken! Makes me thing of something you might see in a book! I'm curious if you kept some notes as you went, so you could remember that this was an "A" version, that was a "C", on so on? I don't think I would remember it all.
I know what you mean about taking pictures for too long. I spent about 3 hours at the little museum here, and was pretty much done for that day. I exhausted both my batteries, (they go fast in flash mode) and was surprised that I came back with way less than a 100 photos.
I have to post a few more of those, but later as I don't want to steal your thunder of the moment! Bring on more pictures!
