The league is part of DC Bocce's Premier Divisions and registration ends on March 15. (Full disclosure, I've played in the Premier League for awhile at Vinoteca and it's a lot of fun.)
The league will also have specials at Lou's City Bar, which is practically adjoining the courts, before and after games. DC Bocce has also has other Outdoor Leagues too around the metro area.
Now the only question is why isn't bocce an Olympic sport? It's basically more accessible curling.
