Today I made a quick cart prototype with only one wheel. It will make walking narrow trails easier. The cart will be constructed from branches that I find on location. The cart is mainly a rig around my giant backpack. I still will be able to carry my backpack, to hitchike for example, leaving the wood behind and only taking the wheel and axle with me. When in need, when loaded with dog food for example, or when walking trails, I can construct another cart from branches that I find.
