Close call

I am sure those little metal walls on the edges of a sidewalk have names, but whatever. I am not a fan.

I went for a walk at lunch, and because I wasn't paying attention, drove of the sidewalk. I couldn't get back on the sidewalk  because of one of those walls.

With my speed up, I got back on the sidewalk, but then lurched all the way across the sidewalk and stopped with one wheel off the curb.

Luckily, a security guard saw me and helped pull me back safely.
