"I see people all over the city. People are leaving them everywhere," he said. Lisa Doig said she has seen people riding them with babies strapped to their chests in carriers, and has had run-ins with careless riders. "Three young men zoomed up to me yesterday [May 20] as I stood on the sidewalk on Caron. I am all of five feet five inches and 115 pounds. They zipped around me onto the grass when they got just a few feet away, and when I said, 'Hey fellas. You aren't supposed to be on the sidewalk on those, eh'. They F-bombed me like crazy and made baby crying noises," said Doig.
