yeah...
u don't think theres a safe way of learning to climb without having to work as a groundie for ever?
No... actually, there are lots of ways to learn, but OTJ training gives you the chance to see it in action, up close, on a regular (not once in a while) basis. I really don't care how you learn, but you will appreciate it much more and be a better and safer worker if you learn the right way first, rather than developing bad habits and having to relearn it later.
I understand the thrill seeker aspect of climbing. If you have been here a while and read some of my past posts, you would know that I am a past mountaineering (rock climbing) instructor. I also used to race mountain bikes and ski the backcountry. Thrills are fine for entertainment, but dangerous TO OTHERS in tree work. I get a high out of climbing. But that is from Rec Climbing HIGH trees. I do that to keep from looking for thrills while cutting. Cutting, whether trimming or removing, should be a thrill-less methodical exercise in the physics of gravity and the biology of plant species. We learn how different woods react to specific cuts and tie in methods. And we try to apply that knowledge in a way that protects life, health and property.
I encourage you to seek thrills climbing trees. Just do it while leaving the saw on the ground until you are better aquainted with the methods and the tools.
Have fun! Just not while toting a 4HP, 12,00 RPM, saw...
Good luck! It is a blast...
