I always liked this photo I took quite a few years ago and have scanned from a photographic slide. It shows Jim "Crash" Kennedy rappelling down the 200-foot entrance drop in Cueva Infierno on the Camotera Plateau just outside of the little town of Laguna de Sanchez, Mexico. It was a pretty pit and has a large colony of rare nectar bats in it which we were there to study. And no, he didn't drop something, that is his pack tethered on a rope just below him. Having a heavy pack full of scientific equipment on your back can throw you off balance on rappel so having it on a short leash below you is much easier.
Testing out this photo idea I had here on the blog. I am thinking the sign on the door is too small but that is the real sign on a real school door and a real robot from Marshall High School's Robotics Club Team Gryphon Robotics: Team 5549
