One of my favorite things about geocaching is finding unknown green spaces, even small ones like this. Who knows why they left this little corner of the field that became a GRTC park and ride alone, but it's a cute little spot to stop and think about things. Coordinates should be fairly accurate, and if you've found a few caches narrowing down the hiding spot should be pretty easy.
A little bit of walking necessary, but the parking should be obvious.
And a quick nod to Andyw3901 for FTF!
