The wheel.

Hi, I'm Tim the guy with the wheel accessibility blog, called Mightywheels.ca If you have kids, I think you have used a baby stroller on our horrible uneven sidewalks, parents pushing baby strollers aren't the only people who find the sidewalks a problem look at the people with wheeled walking aids for people using wheelchairs. I'm in a chair and I want to do something about it. please email your thoughts about this.
