So, I'm writing this after cooling down a bit, but not fully - so please bear with me. We just spent over $7K on redoing our yard(only 1 week in the growing) and we already have a major pest. PEOPLE. Someone has already deliberately drove over it with a vehicle(right through middle of our yard I have .38 acre) and about a half hour ago a kid rode over it with a bike. Very sad I'm in a respectable neighborhood too, but have a corner lot that I guess the new shortcut is much beloved now. With 4 inches of loam they both sunk in pretty good so I have 3 nice ruts going through my still growing yard. I have so far hid spikes in the only area a car can come back in - but not sure if this will bite me in the ass if one does attempt to drive through again - I can see this person(s) driving through getting a flat and running into a tree and I get in trouble for it. So, sorry for the long rant but any ideas of any safe deterrents without putting up a fence?? At this point safe isn't a necessity as long as it is legal. Thanks!
