Unfortunately, about all you can do with a 70' hank of bull rope is cut it up and splice up some slings. Might be a good deal for someone who wants to practice splicing double braid.
yeah its a shorty, for a trunk it could be used to. 20-25' trunk... Thats where most of your big wood is anyway, closer to the ground. No need for a 100'+ 3/4" line.
