You'd be amazed at how many idiots don't know that you DON'T have to have a blue placard in your car to park there. If your license plate the letters "DV" on it here, it's called, "You can park there."
I ran into this years ago. I'm a DV, but since I get around well, I RARELY park there. If I do, it's virtually always because there's nowhere else to park (e.g. like Christmas shopping). I don't do it just to do it.
A few years back in my old apartment, I came out to my car and found it keyed by the fuel tank and a nasty note on it telling me what a jerk I was for parking there without a permit.
The fact this idiot didn't know the law didn't stop him from thinking he was Barney Fife, which is sort of 92's point here. And.....that was the only time in two years there I parked there and you wanna know why? Because there was nowhere else in the block to park!!
I don't like it, either, but just let it go for Pete's sake. It reminds me of Jesus telling the Pharisees how they tithed of stuff they didn't even have to but neglected the weightier matters of the law.
