Unfortunately kids get away with all sorts of things these days
yet a garden hose strategically located helps or a pump action
watergun full of vinegar gives them a teary get away.
I got a bunch of bad mouthed tarts that often sit on my front yard
eating junk food the sprinkler went off with fury and they havent
been back for months.

The best things ever is a speaker playing on a loop a high or low
frequency buzz that anyone over 18 cant hear, they use them all
over the world since starting in Japan to stop kids hanging out
at convenient stores and annoying customers.
