The Museum of Science Fiction is hosting  a 3 day Sci-Fi and Cosplay convention at the Washington, DC Inner Harbor this weekend.  It’s a nice little convention so far and worth the money, $35 for today, $25 tomorrow or $50 for both remaining days.  Parking at the Harbor is $16 for 12-24 hours.  They did a poor job of marketing it but so far the programming and guests are pretty good and the facility is great.  Check it out if you have a chance.   http://escapevelocity.events/
