Check out the one in Whitesburg at Banning Mill.They have many different ones,cabins,horses.So where is the closest zipline to Marietta? I've seen one at the top of amicalola Falls by the hotel.
Actually the closest ones in my backyard but it's 80 ft tree to tree. I have a stop block rigged up with a rope through a pulley to a 15 lb dumbbell weight. What could go wrong?
