All of the museums close at 530 and aaron riley and I ducked into the natural history museum at 525.. I wanted to check their gift shop to see about getting a picture frame for my collection. I had been wikipedia' ing about the hope diamond earlier in the day so we rushed upstairs to see if we could find it and came across the 45 carat, blue monstrocity.. If you get a chance, read up on the diamond. Its got an amazing history behind it.
