Thank you so much for your help.

I drove my car and got it wedged on the low barricade and totally panicked because I thought I had irreversibly wedged my car on the barricade, and the scraping sound really scared me. The barricade prevented me from opening my car door so I couldn't even see how to fix it.

It was incredibly thoughtful of you both to get out of your cars and help me. I may have done more damage had I handled it on my own and you guys helped me get out of a real pickle - and my car wasn't even damaged! Thanks a million and have a great day :)
