what about bamboo?
My gathered end hammock has a "tube" that originally had the tie offs threaded through, which I dont use, instead I replaced the tie offs with a whipping. I wonder though, would a bamboo pole through the hemmed tube work if tie offs were placed at either end of the hammock, on the poles? Bamboo is pretty strong, however the force/weight migh be too much. I'm approx 165-170 LBS.
maybe cary along some hardwood dowel? (not talking UL here, just comfort and possibilities)
