The Segway Golf Cart
I think this is a great idea! I would definitely rent one of these instead of renting a golf cart. All it would take is one person renting the Segway out per day to pay for it too as far as the golf course is concerned. By my math - the second guy to rent per day would be pure profit (assuming a $20 rental and 6 months of golf per year).
I just hope that the guy golfing in the picture is right handed (for the sake of the second guy).
