Here in Florida, 1" wide straps are required, even for the tarp, in State Parks. And this is only for a 1 year hammock trial program. That's required only around the tree if course, not throughout the ridgeline.
This is good to know! I am hanging in Ft. Clinch at the end of the month. I have some straps I never used on a DIY I can tie to my lines from my ENO ProFly, but there is such little tension in a tarp, it seems a bit like overkill. I'm still new to hanging so forgive me if I'm wrong, but can the tension from a tarp line really do damage to a tree?
