Hello! I am not from NJ but just started horseback Geocaching. We found our first offical cache today! We got into it because we accidently found a letterbox while on horseback. Next thing the boyfriend bought me a GPS and now we are on our way! There are at least 4 hidden in the trail area where we currently ride, BrandywineCreek state park. It is next to wilmington De, has plenty of places to park a trailer, I recommend coming up for a ride!
