Princess,
I'm not a newbie, but I just wanted to welcome you to the biz. It can be hard work, but it's worth it when you make it to the top of the tallest tree around, stop for a breath, and enjoy the view that few people ever get to see.
You've got a huge head start over what most of us had when we started just by finding this site. I guess you'd say I'm a veteran climber now, but I still get to learn new things all the time by mixing with the world's best climbers and arborists in cyberspace. I climbed a good two years before I even heard of a Blake's hitch, split tail or knot tender, much less the advanced tools and techniques I've since learned about.
So keep reading and learning, and enjoy your career. Again, I'm glad to welcome a new member to our rarefied community. As Tom Dunlap used to say, Strong Limbs and Snug Ropes!
Keith
