I went to a cache here on Long Island that was in a busy park and about 20 feet up in a tree. It was not an easy tree to climb and there was no way I was going to compromise the cache in front of tons of muggles on a warm Spring day. I went back again in the late Fall in the middle of the week. Hardly any muggles around this time but I still could not get up the tree. I found a long broken tree branch and a 6 foot metal fence post and shoved the branh into the end of the pole. After several attempts I was able to unhook the cache from its nail high up in the tree. After logging in, getting it back to the exact spot was impossible but I did manage to get it attached a couple feet away which was good enough.....Sometimes ya just have to improvise!
