I've had it on my calendar since about February! I'm just debating on whether to go on Friday or Saturday. I went to both the Philly and Baltimore shows on Friday and was a bit disappointed that quite a few of the vendors were just arriving/still setting up by the time we were leaving (between 3 and 4 in the afternoon). I'm wondering whether the DC show is a big enough deal that the vendors will all arrive and set up early? My fear for going on Saturday is that all the really good stuff will be gone by the time I get there!
