The speed limit is clearly posted along Town 'N' Country Boulevard in Tampa.
“The good one. The good one," said Lewis Arana who got a 'thumbs up' from a driver.
But this grandfather rarely gets a thumbs up.
"Slow down!" yelled Arana. "See it!"
Most drivers are flying a different finger.
“They hit the brakes. They know they are going fast," he said.
“Sometimes they go over 50. 55 down the road, 60," said neighbor Luis Salgado.
The stretch of roadway, about 3/4 of a mile, between Hillsborough and Memorial Highway is a racetrack through a residential neighborhood and marked 30 miles per hour.
“I am frustrated. I am tired of this," said Arana.
Neighbors back out of their driveways gingerly here and kids' bus stops are risky.
“My granddaughter tried to cross the road at the corner of Winston Street and somebody don’t stop and almost run over her and I have to run over there but nobody took down the license plate," said Arana.
This grandfather says he's called the Hillsborough County Sheriff's Office multiple times to complain and even asked for speed bumps.
“Well, I think about my safety and my neighborhood’s safety," he said.
He settled for his own kind've speed trap.
“He’s been out here for a couple of hours and we can already see the difference," said Salgado.
It's a speed trap where tickets are paid out by drivers' consciences in the flash of red brake lights.
“People don’t care but we have to do something," he said.
