I don’t think I have ever been keyed but I did have a crazy woman act like she was trying to ram me from the back when I had a Bush sticker on the back of my Tahoe. When she got in front of me and kept slamming on her brakes so I would hit her, I saw a Kerry sticker on the back of her Jeep. She was in a rage so I soon took the Bush sticker off. Now I have a Texas State Rifle Assoc. sticker so now they think I am armed but I am not.
I had a very similar experience about 10 years ago on my way to Reno. I was driving on a rural road in my 4WD F-250 with a Bush sticker on the bumper (next to a country radio station sticker) when a fuzzy headed liberal looking guy in a Subaru with several stickers including "Save the Whales," "Save Mono Lake," "Green Peace," etc. passed me and then slowed way down.
The road had a lot of curves making it difficult to pass him. He kept hitting his brakes at every bend in the road while looking at me in his rearview mirror so I slowed down and let the fool get ahead of me.
He came in sight again as I came around the final bend before the road straightened out. He was still looking at me in his rearview mirror as a deer dashed in front of his Subaru. He hit the deer full force flinging it up and over his vehicle in front of a family with kids fishing in the river alongside the road. As he pulled over with severe front end damage to his vehicle I waved with a grin on my face as I passed him by.
