more thoughts on recreation

Regarding the climbing wall and attaching holds: I did some searching over the weekend and it looks like there are some pretty good products for bonding items to concrete. We're thinking we might we might want to go that route to avoid being sent a bill for reconstruction of the Prospect Expressway when they find we're drilling holes in the concrete retaining wall. The products all claim something like 3,500 psi tensile strength and even more compression and...what's the other one...I can't remember but I think it means twisting. I can't imagine any of us putting more than 3,500 psi of pressure on a hand hold, and as long as we have a rope...Still have to figure out how to anchor that rope.
