I have had to do this before , somehow inchworm my way up safely with Tree gear. Was a Steel pole with enough paint to add a little texture wich gave my slings and safeties a little friction. Fly in the Oatmeal this time , pole is Fiberglass and I'm not completely sure I can grip the thing. Planning on quick test before I commit to job. Any other Treehousers ever climb on Fiberglass ??
