I know this is not up your alley, BUT, have you ever considered branching out? I play golf, I'm the Granny of the Phil and Ted's users and I am so impressed by the ease light weight and maneuverability of your products. I would love you to design a golf cart that is light weight, folds easy and goes over lots of different terrain. Most of the carts are on the market are big, heavy and take up too much space in your car. I think you would do a wonderful job designing this much needed item!
