Here’s one for my biker buddies . . . ever seen a “tree bike”. A guy in India built a gas powered “tree bike” that can climb up the side of trees. It looks more like a carnival ride than a bike. You sit on a seat with a harness facing the tree trunk, then give it some gas, it slides UP the tree. If you’re wondering why the guy invented the “tree bike”, it’s so he can harvest the “areca nut”, a popular crop that has medicinal properties in some parts of the world.
