I definitely recommend Treasure Island. Its an amazing camp with tons of history and tradition as the oldest camp in the US and the birthplace of the Order of the Arrow. They have recently revitalized the camp after nearly having it closed due to severe flooding 2 years in a row. Everything is close together, the program is well run, the staff is amazing, and hey...YOU'RE ON AN ISLAND! They also offer free tubing trips down the river which is very unique among scout camps. You can also go on rock climbing trips to Ralph Stover State Park, canoe trips, and bike trips off the island.
Its a great experience for the boys and leaders.
