Many things going on this weekend

Barracks Row Octoberfest, the National Book Festival (the tent of the states I jokingly call the "tent of best practices" for those of us who work in the cultural heritage field--at least a couple years, each state had a booth featuring its State Library and/or history units), Magical Montgomery, the county arts fair for MoCo all on Saturday, plust the BikeDC event, which is a 17 mile ride throughout DC.

Plus in a comment, BeyondDC adds + Clarendon Day on Saturday and Crafty Bastards on Sunday.

(There's no way I can get my gf to agree to go with me to all these events... See, for me they are fun to evaluate, and to talk to the people at the nonprofit booths. She doesn't get the same kind of charge from those activities.)
