At the Smithsonian Institute's National Museum of Natural History, this woman was working on some fossils in a glass room as people crowded outside to look at her. "Please do not knock on the glass. It disturbs the mammals preparing the fossils." said a hand-written sign on the glass.
Thanks a lot to everyone who commented on my photos, or even stopped by for a visit. The comments have been pouring in pretty fast and I'm finding it increasingly difficult to reply to each individually. I'd rather spend that time in viewing others' photos and commenting there. But I do read each comment individually, and if you ask me something specific, I'll answer that.
