I went to GLAM night out tonight in the 7th floor of Newseum. Unfortunately, I left my bag there, under my seat (in the first row), or maybe in the elevator. It is a blue carry bag, with a smaller black bag in it, and a plastic bag in the black bag, containing some things I bought from Wiki-shop: three T-shirts, some Wikimedia Symbols, etc. So it is very important to me.
