Sail the oceans, sail the air currents in a glider, White water raft, go on a 2 week backpacking hike in a wilderness area, take martial arts, work for a golden glove boxing ametureship, learn to fly a plane, travel across europe on one of those bus route trips, rappel (sp?) down into the Grand canyon, SEE the Grand Canyon to name just a few off the top of my head. Am I overly ambitious?
