In July, a group of 15 camp friends from across the country reunited in Boston for a weekend getaway. They saw the Red Sox lose to the Orioles at Fenway Park, attended a beer-tasting, toured the local nightlife and cruised through Massachusetts Bay on a rented boat. They wore special T-shirts they had made to commemorate the gathering, trying to recreate the tight-knit, fun-loving community they had experienced at the summer camp where they met…as adults, not as kids. Most of the 15 happy campers had met only a few months before in Austin, Texas, at a site for the all-adult Camp No Counselors, a sleepaway retreat where adults play like children and party like adults.
