I wouldnt mind having a sled or a palet like truck to drive my wheelchair on to ride around like a moped. They use to make one that was gas powered called a chair-e-yacht.
I am tempted to buy a power ski unit from zap bike to use with my manual chair. I just have to park it some where or draw it upright behind my chair. jeff richmond, va http://www.wheelchairmodifications.org
