I love these rhymes that promote bicycling etiquette and safety along the Minuteman Bikeway. They feel like they’re inspired by Dr. Suess, and provide a friendly reminder to be careful and courteous.

Kids like to bike; sometimes they stray; help them ride straight; so they’ll have a safe day
Here are a couple others I’ve enjoyed:
Adjust your pace; to available space; note traffic conditions; this isn’t a race.
Dogs are fine; keep them in line; pick up their litter; lest others be bitter
One if by land; two if by sea; say something please; if you’re passing me; or just use your bell; so you won’t have to yell.
