Thanks, blam! As you probably know, there is a very active rock art archeology community here in Texas — but the rock art is mostly in west Texas — a l-o-n-g way from where I live...
I'm reminded of a conversation I had with a Brit the other day. He was explaining to me that from the southern most tip to the most northern point that Britain was 610 miles long. I immediately thought of the milege sign at the Sabine River (Texas/Louisiana border) that says WELCOME TO TEXAS...El Paso, Texas 837 miles. I told him that it (The mileage across Britain) was about 3/4's of the way across Texas. LOL. I haven't hear any more from him.
