If so, you're in luck!
KEEN (Kids Enjoying Exercise Now) DC is a non-profit that provides exercise opportunities for kids with physical and mental disabilities. They are desperate for volunteer "coaches" this Saturday at the Takoma Park pool. I used to volunteer with them when they swam at EMP, and cannot express how rewarding it is. If you think "well, I'm not really a swimmer... I couldn't coach," don't worry-- it's more playtime than an analysis of stroke efficiency :).

I agree! This is a great organization to work with and a lot of fun.
The kids are awesome. I can't make it this Saturday but do have them on my calendar for future sessions.
