Confiscate and destroy the bikes, fine the hell out of them and sentence them to mowing the grass for a year.
When I lived in Broward County, some teens did this same exact thing, except it was done on a Seminole burial ground on their reservation.
The tribal cops caught them and confiscated their bikes and kicked them off the reservation after calling their parents.
They complained to the Broward sheriff’s department but were told they had no authority on Seminole land.............
Many years ago if teens behaved poorly they actually would be sentenced to cutting grass all summer in the cemetery. In those days they used heavy metal mowers that had to be pushed by hand.
Excellent idea.
Rather than mowing I can see these teens getting long, hot, hard lessons in the landscape repair trade.
“sentence them to mowing the grass”
AFTER they do the hard work of tearing out and replacing the greens.
Perfect punishment.
