Little prick turfed my yard last night.

Stuff a few dead fish in his car...the stink will never completely go away.

I like the rebar in the lawn trick though!

A few decorative boulders around the perimeter would work too.

Nobody messes with the roads in my neighborhood....I'm the only one that grades 'em and the last tweaker that had an issue with my "old stinky poluting POS tractor" couldn't get out of his driveway the last time it rained <evil grin>
