Austin Climbers

Greetings!
I would love to hear about classes or any other opportunities to learn tree climbing from experienced climbers in the Austin area.

I have always been inclined to climb, but constrained to trees where I could grab that 1st limb. The use of ropes will be new to me.

I have been eyeballing several tall cottonwoods on Lake Austin for a few years now and my goal is to get up there!

Any info is appreciated!
