This guy is lucky I was driving my truck... I'm not as lenient when it comes to my car.

Normally I would leave one of these posted in a very noticeable spot.. you know, to warn other drivers. Unfortunately I left them in the car.

LOL this is awesome I am so gonna remember that and print those off thats amazing

Stickers
I usually keep a few handy for situations like this
I didn't actually buy them, I got them as a gag gift, turned out to be quite handy.

I am definatly looking at buying some to keep around. My only worry is are they super adhesive cause i dont want to ruin someone elses paint... as id be pissed if someone did that to me

Good thing those Silverado bumpers are tough!

You can always put it on their windshield or something.

Heh, it'* a sierra, but close enough!
The stickers aren't super adhesive, I remember reading they are easy to remove. Normally I stick them to plastic bumpers or windshields, drivers windows, etc. Also only when they are deserved, in which case... I don't really care if it never comes off! Everyone deserves to know these people can't park.

Ugh, the nerve of some people.

Of course, some fox urine in the HVAC air duct would work nicely.

Hmm.. Maybe I have been to lenient...

if people can't park then they shouldn't drive love the stickers goin to have to get me some

Naw, The site says they are clingy, but not adhesive backed. Me, I'm printing as we speak. Nice one!!!!!!
