Yes a aibu with those lovely 3!
I live in a house that is on its own in the middle of field, the house has a long drive way about 1/4 mile you can't pass another car on it, big drops on both sides. The house its self is cut into the hill so it has several levels. There are 4 parking spaces, 2 right out side the front door and another 2, the second level down. If you park like crap on the lower level you can't get the cars out from the front of the house.
Now the person who livid the house before us didn't drive and was the type to say to people come and park and mine and take.the dogs for a walk. The driveway it's self runs next too a footpath, it's not actually the footpath that's the field and not the drive, the footpath continues up the hill past the house. Anyway we've been getting blocked in ever since we've moved in with people parking in our private parking spaces, or just on the drive it's self. Notes/asking people not too doesn't seem to work. It's a popular dog walking route so it seems. So we put up a gate at the bottom of the parking spaces, people just open the bloody thing and still drive in, we've got no parking signs up the works. Or if they have walked up the drive just leave the gate open. We can't really lock it as there is no where to turn around for the Postman/partners clients works from home/or the farmer for his fields.
Aibu to just go out and puncture there bloody tyres?
