Borrow a shopping cart
Desert185,
Maybe in your neck of the woods, but don't try that in the UK! For some completely unfathomable reason, shopping carts in the UK are equipped with four castoring wheels and are impossible to steer!
This ludicrous design has even made it to the airports. I remember struggling with 60 Kg of luggage on a cart going down a zig-zag ramp at Gatwick. The newly-arrived American passengers faced with the same control problem, were loudly commenting on the stupidity of the design.
