Years ago, we had a party here. It's a great place to reserve for parties. Basket ball net, volleyball poles, (im assuming the net goes up in the spring as they were bare today), indoor cooking area, covered eating area, hibitchis, lots of field and trees for exploring (and geocaching). Theres even bathrooms for your event.
This should be fairly easy, the terrain is flat and easy. Could be considered a cache and dash assuming my coords are accurate. :)
I have placed some FTF Trading cards and a TB. Lots of smaller swag like geocaching poker chips, and some trinkets for the kiddos. Enjoy and happy caching!
