Summer camp has grown up. Sure, you can still send the kids there, but there's no upper age limit. Nationwide, more than 800 camps cater to the adult crew. On the grown-up agenda: nature retreats, intensive cooking courses, triathlon camp, and cowboy college. "In this world of being the best one can be, people really want more out of their vacation time," says Nancy Diamond, managing principal of the Camp Professionals, which offers consulting services for camp owners and operators. In 1996, she launched the directory grownupcamps.com, which she spent 13 years running. "Maybe you're finally going to learn about something you always wanted to learn about, or a passion you always wanted to fulfill. It's a chance to take the time to take care of yourself."
