a buddy tried tightening his while about 10 feet up and the entire bottom fell to the forest floor...there he sat, 10 feet above, feet just a dangling...NOT ADVISED

i do what hoosier does, but something extra...i put it about shoulder level and angle it, then I lift myself up onto that bottom platform, then attach the seat portion, this gives me the levelling that i need, but also not having to worry about the tree "thinning out" as I climb
