I like this thread, there are some really interesting photos! I did a 41.45 mile ride yesterday (longest ever!), with, if Google My Tracks is to be believed, 4967 feet of elevation gain. My legs were burning when I got back home, and in the final 5 mile stretch I dropped to the lowest gear at the slightest incline. I really should stop more often to take photos, and maybe even carry a proper camera. Here is the sole photo from my ride yesterday - San Andreas lake in California seen from the south.
