I almost fell out of a climber....the top section let go when I was still setting up which left me standing on the lower section.....normally the sides of the upper section give you something to brace against while yur standing.... it was a pretty uneasy (and Noisy!) moment that I care not to repeat!
I build myself a large wood tower this year on my land and haven't even bothered going tot he public lands yet this season...so no need to use the climber!
