How would i go about joining a nudist colony?

First of all, do some research into the naturist/nudist lifestyle. Among other things you'll learn that "nudist colony" is an outdated, antiquated term. They are called resorts now. Some resorts do offer residence on the grounds, and the details (seasonal, year round, own vs. lease, etc.) will vary from place to place. I haven't looked into moving into one but in the past I heard they are rather expensive. However, since you're only 16 they would not allow you to visit without being accompanied by a parent or legal guardian. Once you're 18 and legally an adult there is no such restriction, and until you reach that age you'll have plenty of time to look into the information you want. Sources to find lists of naturist resorts would include the American Association for Nude Recreation (www.aanr.com) and The Naturist Society (www.naturistsociety.com).
