At least ten times a day, I am annoyed, frustrated or downright angry at someone or something on the road in my travels. Mind you, my travels aren't all that extensive. If you take the amount of miles that I drive, divide it by the number of idiots and clueless people on the road & then multiply it by all of the unusual things out there, it equals a wealth of subjects to write about.
Until I have front and rear facing rocket launchers mounted on my car, a blog should do just fine.
