Wondering about fashioning a single wheel or double wheel cart that I could hook to a packgoat or two and I'd balance the rear end to carry game out of the woods. I'd have to lift it over logs, etc.. They make game carts with a center wheel and two handles on each end for two people to handle. I'm getting older and fatter and am looking for a means of extending my hunting range for elk and not have to bone out. I can get myself down and up these steep grades, but packing out is problematic. Would like to get the goats to provide the forward momentum. Slopes as steep as 45*. Maybe 2 wheels side by side so the cart would be self supporting.
