Still in Museum Mode

I must still be in museum mode, because I went to the Natural History Museum last night to sketch after work. It's open until 10pm on Wednesdays which gives people the chance to go up to the observatory to view the stars and such. I stayed in the rest of the museum to draw. There weren't a lot of people around, except for a very loud birding group in the lower level. I overheard one person say that during a trip that a particular person was in their group, and it was hard for them to view birds with how talkative that person was. Seemed to me that they were all pretty talkative! :D
