A Sleepy Hollow man made a sign for the back of his bike after seeing dozens of people not wearing a mask on the Gov. Mario Cuomo Bridge recreation paths.

Mike Doorley says the bridge path isn't very large and face masks are required, but people aren't complying once they reach the entrance. He says he sees only 50% of people wearing a mask.

Doorley says he created a sign reminding people to "mask up" and now he pedals with a purpose.

"In New York state, if you're over 14 you aren't required to wear a helmet yet virtually every bicyclist wears one," Doorley says. "You are required to wear a mask and like I said, far too many are not. That says in respect to recklessness, they're not reckless about their own lives. When they're not wearing a mask, they are reckless with other people's lives."

The shared path is only 12-feet wide, so keeping a 6-foot distance isn't very achievable, which is why masks are required.

Gov. Andrew Cuomo tweeted last night, "The mask goes over your nose. Some people don't seem to realize. The state also has a table set up on the Tarrytown side of the bridge providing free masks."
