This is crazy but one summer in Homer there was a fire and traffic backed up and one crazy lady cut in front of me and almost hit me and I gave her a light beep on the horn so she would not hit me. So she whips her vehicle around and speeds up to me, follows me in a parking lot and blocks the driver door and I have a disabled passenger with me in the front seat. She proceeds to get out of her car and loudly berates me and will not move and let me out of my jeep. I sat there and called 911 and the cops came and made her leave me alone. The cops did not charge her with anything and they told me she had some "major" personal problems lately. I'll say. So I agree with you I now carry pepper spray handy in the jeep. I never said more to her during her rant but ask her to move so I could get out and  continue into the store and defuse the situation. But I will never be pinned in my jeep again by some lunatic.
