Hi All!
Last year I was putting up calendars of events of local activities on a monthly basis. But there are so many great sites that already list the things to do around town, that I decided to put them all in one place as a resource.
Here they are:

http://www.playseum.com/
http://www.thepuppetco.org/
http://www.adventuretheatre.org/
http://www.friendsofhuntleymeadows.org/
http://www.washingtonparent.com/calendar.php

I hope you find this list helpful!
