My thanks to the sponsors of the Americans with Disabilities Act (ADA). Because of this act, almost every curb in Phoenix has a wheelchair on/off ramp.
In the 30-40 miles I have glided on my Segway so far, including much of that through construction areas, I have only had to negotiate 1 curb. Just 1. That's amazing to me.
Another long Segway glide this morning, from the U-Haul dealer to my work, about 5 miles. Took about 33 minutes. No problems.
