Since the weather is outstanding, how about BBQ again?  Montclair park seems centrally located to almost everyone.  I can bring buns, juice, a few beers and some dogs.  Anyone else?

Montclair Park (Oakland) - Montclair park has a fenced-in totlot as well as a bigger playground for bigger kids, plus grass to run on, fake horses to sit on, geese to get bitten by, and a small lake to fall into.

Montclair park is between Moraga Ave and Mountain Blvd, just north of "downtown" Montclair. It's the park just above the star on this map
