Foraging and not field picking, I have picked a third-bucket by myself. Made three pies from it and some ice cream with those blackberries. The most I've ever seen foraged as a group was 1 bucket in an afternoon. I suppose most of us just forage enough to eat out of hand, a small amount.

I've had better luck with mushrooms. Once picked an entire large grocery bag of queen boletes in Maine...and could have taken bags more but...what would have been the point?
