Want to feel like you're part of a super-secret society today? A super-secret naked society? Sign up for the Heartland Naturists' annual Sun Run, a clothes-free 5K run and walk through an undisclosed location in McLouth, Kansas. Once you sign up — $15 for nonmembers of the Heartland Naturists ($20 for nonmember couples and families) — you're given the top-secret location. If you're new to exercising and lounging in nature with a group of naked strangers, here are some pointers. Wear sunscreen. (Last year it was rainy, but you don't want to bake your sensitive bits if it's a scorcher.) Wear shoes and socks. Leave your camera in the car. (This is a big one. Naturists, the politically correct term for nudists, strive to make everybody comfortable, which is hard with creeps trying to snap shots for their spank banks.) And, finally, bring a dish to share for the post-run potluck. After sharing your nude form with everybody, you may as well share your mom's recipe for creamy mustard potato salad.
