With Brain & Pinky, Eikenhofjes and Xizat I travelled 11 days through the USA to find some very old caches. On our 2nd day we visited Iron Horse, the APE cache and Geocache GCD. We left our motel very early and drove 1.5 miles to the Robert Morris Earthwork, created in 1979. We all searched, but Brain found the box.
Thanks and cheers!
