I took a 7 week coast to coast road trip after being laid off from Boeing. I didn’t have a camper but realized that being able to pull off the road at a rest or truck stop was the way to go to make the trip affordable. With a few sheets of 1/2” plywood and misc. hardware this is what I came up with. The effort was well worth the time and materials.
Deep in the rainforests of the Indian state of Meghalaya, bridges are not built, they’re grown. For more than 500 years locals have guided roots and vines from the native Ficus Elastica (rubber tree) across rivers, using hollowed out trees to create root guidance systems. When the roots and vines reach the opposite bank they are allowed to take root. Some of the bridges are over 100 feet long and can support the weight of 50 people.
