George is still running the show on the ground. Shelter Tree earned it by being a pillar of the southern New England arb community for years. Still a great place to stop by, browse the gear and catch up with other tree professionals. They're setup so you can get on rope and try harnesses etc.
On a selfishly personal note I was miffed when a former Shelter employee got their cat stuck in a tree in a swamp. They had a Shelter associated climber with serious cred take a look and say "Nope, not going in that swamp", then nothing was done for at least a week and a half. Everyone at Shelter knows what I do. I heard about it through my beautifully crazy cat rescue network and contacted the cat owner. On site looking through binoculars I observed the cat hanging like a dishrag over over a crotch in a red maple. "What? No one would go in there? Time to make it happen". Ok, I've spent my life slogging through what passes for swamps in New England, not a big deal at all. Cat was retrieved, mud washes off, gear dries. Next time I'm at Shelter I'll be checking in on that, "Dammit call me when this stuff happens!" ;-)
All true  Here's the vid, a primer for a challenging cat in a tree rescue. That boy was skinny and weak, stumbling as he walked branches and came close to falling out when he went to the ends trying to keep distance from me. I lie to cat owners constantly during rescues, not really but I put as positive spin on it as I can muster, they are often freaking out watching their cat stumbling around at height. Once the cat's tail goes up straight like a flag pole (shows relaxation) I know I've got them, still... patience gets the cat.
