One other piece of advice...don't try to hide your license plate. It is so stupid. What do you do when go driving? Nobody is coming to hijack your car...except your neighbors.
I was at a thing called "Cruisin' Grand" last year in Escondido, where people basically park and show off their cars. I was taking a picture of someone's Shelby Cobra and he ran over and yelled at me for getting his license plate in my photo. I mean he was apoplectic. Face turning red and everything. It was hilarious.
