Sorry , didn't mean to get legalistic on you ie: "freak accident" or otherwise

Tree climbers have to be very clear about what we're talking about, life or death can depend on it.
I'm sure you have great skills, no need to defend your ego. There are many trees that you can climb, there are many that you cannot, you're human (I assume). If you do a search on Bareroots in the TCI message board you'll find a kindred spirit. Bareroots has learned how to climb with rope, I'm sure he enjoys a free climb now and then, as I do.
Arborist professional organizations are the only ones I know of that hold tree climbing competitions. They require rope back-up because people have died in competition. Also, arborists need to be encouraged to climb safely, not the other way. There are already too many ways to be killed on the job.
Recreational climbers are generally non-competitive, mileage will vary from climber to climber. I like a challenge, and find many everytime I climb. We're looking for quality tree time, not a race to the top.
