Straight from the courthouse to you -- I haven't even read this yet, but here is a copy of the lawsuit, which was filed today in federal court in the Eastern District of Texas.

                          If you ever plan to motor west,

Travel my way, take the highway that is best.

Get your kicks on Route 66.

It winds from Chicago to LA,

More than two thousand miles all the way,

Get your kicks on Route 66.*

OK, kiddies -- jump into my '55 T-bird, and let's take off on old Route 66, from Chicago to L.A., more than two thousand miles all the way! If you promise to behave, I'll let you ride with the top down.
