When you own a Segway, you become a sidewalk connoisseur of sorts. You really notice anything odd or unusual or broken about the sidewalks. It's more noticeable than when driving, because roads are generally in better shape than sidewalks, and cars have shock absorbers. The susceptibility to bad sidewalks is probably my least favorite thing about owning a Segway.
And my goodness, I thought the sidewalks between my current apartment and Microsoft were bad enough, but the sidewalks on the way to and from my new place are abysmal. There are holes in the sidewalk, months' worth of dead leaves and tree parts, and mailboxes right in the middle of the sidewalk. It's bad enough that it's basically all uphill from my new place to work; I went through three quarters of a charge on my brand new battery with just one trip yesterday. I've tried both sides of every street by now, and neither is any better.
