Based on the votes, comments and emails I received, I think the best day for most is Saturday, May 8. (So sorry @Slim! I'll try to make sure the date in June works for you!)
Here are the details:
-Who's Invited: Anyone in the DC area who is interested (bloggers, commenters, Ask Moxie readers and silent lurkers), spouses and kids
-Day: Saturday, May 8
-Place: Be with Me Children's Playseum in Bethesda (directions)
-Cost: $5 per person, any age
-Other Info: Be sure to read the Safety Policies, Playseum Manners, Sickness Policies and Food Allergy Awareness pages! This place isn't like the At Play Cafe we previously went to in that they ask you to be within arms' reach of you child at all times.
Please leave me a comment or send an email letting me know if you can make it!
I am tentatively planning a June meet up, also. I may even try to do one a month in order to give us all some momentum.
