RE: lag bolt steps
I bought a really mean cuttin' drill bit and actually use the 7" Grade 8 lag bolts as the steps. I can charge up the batts on my cordless drill and go out and put in a couple trees worth at a time. Whats also very nice is that you can get up to over 20+ feet for less than the price of a couple screw-in steps. I usually have many trees "drilled" during the post season but it only takes a couple minutes. Of course I try to be selective on the tree species I select to be drilled. I always try to drill only my "scrub" trees and stay away from my Oaks, Walnut, or any other tree of value to me or the wildlife.
