OK, OK, so it's not that great a song, but the title and lyrics seem to fit this cache: a neat little place with some history behind it. The plaque near the posted coordinates has more info. Also be sure to check the attributes before heading out, and bring your own writing tool.
Note 10/9/13: There has been at least one other geocache nearby here previously (GC1Q0XF). Some of the concerns why that cache was archived should be alleviated if you heed the instructions below:
The container is in plain sight so you shouldn’t need to move anything to find it, but you might have to look around a bit. It is about the size of a child's fist and you should not need a special tool to open. The cache seems to move a lot over time, so I ask that you PLEASE REPLACE WHERE FOUND! Also probably not the best cache to seek if you're arachnophobic...
Good luck!
