So let’s start off and say that this is probably going to be pretty difficult for some, as it is "slightly" evil. And with the tree cover, gps might lead you astray.
It is in a place that is not very busy (well most the time), so you can look without being bothered hopefully. Its in plain sight, and you dont need to get behind it.
I hope that you have to search for this enough to get frustrated, and then find it before you are to frustrated, and you are able to have an "aha!!!" Moment... As I think those make some of the most fun caches.
Anyway, Happy Caching.
