Last year I was driving through El Paso with my travel trailer. I noticed a sign that read: "Drive Texas Friendly."
The campaign must be paying off, for they did drive friendly. When the slow lane gave out and I had to move to the left and put on my signal, and even though the traffic was heavy, the other drivers would blink their lights and make a spot for me. The same was true when a new lane was added and I had to move back to the right.
