You Can Get Arrested for That: 2 Guys, 25 Dumb Laws, 1 Absurd American Crime Spree by Rich Smith
The premise here is the absurd dumb laws that are actually on the books in some cities and states in the United States. You can access a listing here, which may not be the exact list the author used, but almost all of the laws he broke, or attempted to are listed.
The author and a friend head to California for a cross-country trip, all the while attempting to break some of the more ridiculous laws on the books in several states. At first he has only a smattering of successes, most of the time with rather boring results. It seems to me tide turns about midway through the book, when the unfortunate coincidence of their Cornish flag they are displaying (they are from Cornwall in the U.K.) has a resemblance to the flag that a local violent gang displays. They are briefly met with hostility by local police until the error is cleared up. It is at this point that the book started getting more interesting.
All in all, its not an entirely satisfying book as far as road trip books go that I've read. But if you are unfamiliar with the strange laws, or just like the idea of breaking laws just for a laugh, you probably can't go wrong with this one.
Rate it 6 stars.
