While I don't have first hand knowledge for this year, normal blueberry season start time is two or three weeks away. The season normally runs late July into August.
There is still strawberry picking; we were at Smith's in Gilford earlier this week. The makings for dinner that night: a bowl of just picked ripe strawberries sliced with a little sugar, a batch of home made biscuits and a bowl of just whipped heavy cream.
