think of how much money the gas companies could make if they switched to selling coffee for fuel instead of gas - wait guys, am I on to something here

Where do you suggest he carry his cane while he is in the wheel chair?

Side to side so it takes out the kneecaps of everyone around him?

Front to back so he can gut punch the ones in front or behind?

Or maybe out to the side? Where it won’t hit anyone?

Lets go further, if he holds it to the side, should he just hover it stiffly in the air while moving?

Maybe the answer is this is the easiest way to hold the cane while moving without taking anyone out or forcing someone else to carry his stuff.

Not everyone who is in a wheelchair is completely unable to use their legs. Many wheelchair users can stand or walk, but not for long periods or long distances or without assistance.

He might be able to stand with assistance and is carrying the cane himself for when he wants to stand.
