i am looking to plan a weekend getaway for 15-20 people. we are looking at the weekend of june 22/23 (that is friday and saturday night). we will show up friday evening, leave sunday morning. we want to be on a lake where we can rent a pontoon boat or two. not necessarily right in the heart of the dells, but within a reasonable distance (25-30 minutes drive is fine). can anyone help me? thanks!!
