Ten to fifteen times at your grandfathers home? You didn't mention over what period of time. How many people live in his neighborhood? If they are attacking others at even a fraction of this pace, that's a lot of vandalism. Or, is there more to this story?

 

Yes yes dig a hole/ditch so it gets stuck and ****ed up. Or put some nails through plywood and drop it in the grass.

 

Stop screwing the guy's daughter?

 

rofl, i'm in for the ditch idea!

 

Definately need more info. I take it you think it is some kid or are we talking a real piece of work adult. I would approach my revenge plot differently given what the answer to that is.

And if there is a history we definately need the details.

I don't like to mess with people, and treat everone the way I would want to be treated. But when someone starts a battle with you for no reason, I believe you finish it quickly and in a way that says "Don't ever even think of messing with me again."

 

i still favor the idea of digging a hole and covering it with leaves...

 

Caltrops

 

i say spike strips. your dad could also get a sturdy ass fence (like made of brick).

 

dont the police have little spikey things they drop in front of cars when theres a high speed chase to pop their tires and stop them? how about those....

 

Since it's private property, I still think lining the border with home made spike strips would be effective. Look for where they've been leaving the road for the property and dig a small trench and bury some 2x2s with nails sticking through them (facing up).

Big rocks lining the road would also work.
