Why? Its always sunny and dry on the coast!
Best joke I ever heard about Oregon Sunshine was the one about people from Oregon don't tan, they rust.
All fun aside, I used to live in Denver, Colorado and there were a lot of rust buckets there, and when I live 2 blocks from the water in the Ft. Walton Beach, Florida area, I saw a lot of rust in those vehicles as well.
Not all vehicles in those areas will die from skin cancer, but there is a higher percentage of them that will when compared to places like the Arizona Desert or the California Central Valley.
