Earlier this year, I had an H bar painted across my dropped kerb because people kept parking over the edge of the dropped bit, meaning I couldn't get in or out of my drive (the drive is narrow and at an angle on a very narrow street with cars parked opposite).
So far, it's pretty much done the trick. But today I went out for an hour and came back and someone has parked a good foot or so over the end of it, meaning that I can't get my car off the driveway. Unfortunately for them, I was not using the vehicle which was (and still is) parked on the drive, but another one. :)
So I've parked across the rest of my H bar. There's now enough room between my front bumper and their rear one to get a matchbox in. There's about a foot between them and the car parked in front of them.
Today is my last day at work for 2 weeks. Do you think I should have an early glass of wine to celebrate?
