Mr. 0: I had a free moment this evening so I stopped up to see if maybe the terrain had changed. Everything mostly looks the same, however the area around the cache is completely covered in poison ivy. The only way to get to the container is to crawl through a bush of it. I also noticed that the area has become much more of a party spot that it used to be.
I'm going to give this one up. It was my oldest active, favorite hide, and most favorited cache, but given the poison ivy, graffiti, clothing, alcohol containers, and drug paraphernalia near the cache or along the path, it's no longer a place I wish to draw people to.
The container may or may not still be there (it's like Schrodinger's Geocache). I couldn't get close enough to spot it. I'll stop out in the winter once the PI dies back and remove anything that may be there.
Thanks to everyone who stopped out, and congratulations to the many who chose this location to celebrate various milestones.
