So many people get caught up in the fact that "you don't have to register the copyrights to your work because it's copyrighted the moment you create it." However, if you want real protection and legal hold when it comes to your work being stolen (copyright infringement), it's worth the few minutes and few dollars to register it.
For the past five years, I've driven all over the country documenting America's rest stops. With drive-thrus and gas stations at nearly every exit, rest areas are losing the fight and are vanishing in nearly every state. Shortly after moving to Texas from California seven years ago, I was struck by a recurring sight - the humble rest stop. The more of these roadside parks I saw, the more inspired I became - there were tables shaded by faux oil rigs, teepees and wagon wheels, and geometric shapes echoing classic mid-century design.
