The Fall Ball is a contra dance held annually at the Town House in Peterborough, New Hampshire. It runs 12 hours, from noon to midnight, with four bands and callers in turn. The hall is huge, and has a wonderful balcony. It’s a real pleasure to dance in, and the dancers are incredibly good.
I’d 
never been, before yesterday. The experience was wonderful, and I would go back in a heartbeat.
The balcony allows a large number of people to sit out, watch, and socialize. There are diners and cafes around, and it feels more like a festival. In contrast, the Dawn Dance is almost a religious experience.
For those so interested, I’ve posted a gallery of the best photos from Fall Ball 07.
