@loren At my park, I put ours on the copier and kept records. Some did show up repeatedly. Visitors got in on the fun and brought them in. We returned each one to its found location after copying. Some ladies got a special visit with our nature center educational turtle Don Juansta. Even the rangers were pimping for him, picking ladies off the road on rainy days. Don was always willing to oblige them as he'd gotten desperate enough he was humping the toes of peoples' hiking boots!
