These days grown-ups seem to be getting interested in activities normally reserved for the kids in their lives. It seems to have started with those kickball leagues now adult coloring books are having a moment. In fact, several adult coloring books have sold millions of copies. Then there are the camps and pre-schools. Adam Tichauer runs a camp where adults can get away from it all with no distractions in an environment very much like the sleep-away summer camps many of us went to when we were pre-teens…think archery, capture the flag, tubing and other activities in the great outdoors. The camp is called Camp No Counselors, and it’s an adult sleepaway camp. Tichauer runs adult summer camps around the country, including one in Lake Delton, Wisconsin that drew a lot of people from Chicago earlier this year. (Flickr/Jelle)
