I couldn't pass this up when I saw it in the woods where I use to swing on vines around 45 years ago.
We called them grape vines but they did not bear any fruit but me and my buddies. We would swing over a hill drop down in the leaves several feet below. It seemed like 20' but I am sure it was less but it was enough to get hurt if we did not roll when we landed.
So I am still playing with them after all of these years.
