where have all the elderberries gone?

Anyone know the best spots to pick elderberries in Somerville?   Crab apples, cherries, and other assorted fruits and berries appreciated too -- I know they've been planted in many of the public parks, but I don't have a good sense of where to start looking, and there are plans afoot for a grand bike ride to go make jam out of them.

If you have fruit trees on your street that you don't mind foragers, please drop a line and point me in the right direction!
