I have done quite a few and have yet to have a bad experience. However, there have been some that just didn't feel right and I declined. As stated above, all my swaps have resulted in good friends. Bottom line is don't try and do one at the last minute. Develop a relationship with the person and if something doesnt' feel right, it probably isn't. I have been to Alaska, Montana, and Colorado. Got one planned for next fall in Colorado. Can't wait!
