I scouted out a location for a cache in a small park nearby where I live. I went through all the process of contacting to local parks and recreation director and getting permission (he knew about geocaching and said one of his coworkers geocaches, but I didn't get his screen name). I went to the park with cache in hand and was ready to place it when I discovered an apparent transient had pitched a tent about five feet from where I was going to place the cache. I left the area without placing it and contacted the director, telling him that I hadn't placed the cache and why I hadn't.
