I checked and the Weirs Community Center, just up the hill from the Weirs, can be rented for $100 plus a $50 refundable deposit. The contact person is Connie and she can be reached at 366-5185. Capacity is 150 people, plenty of parking and it would also be accessible by boat.
On another note, I think a possible recipient for any money raised is the Lakes Region Conservation Trust. Go to
www.lrct.org and click on "Protected Land". The list is quite impressive, including locations on Winnipesaukee.
