What concert, Dolly?
Each Sunday Evening (and a select few Monday's on long weekends) Hudson puts on FRee community concerts.. good groups. THey pay a lot for them. (not just the gargage foursome that practiced twice). I can get you a schedule.
Bring chairs or blankets.. food, drinks (be descrete with alcohol). Ihave never seen it forbidden but that is because most do NOT flaunt it)
Usually about 2 hours long
