OK, this is now one of my favorite place to ride in Texas. It's a bit of a trek, 8 hours each way, but if you want a long weekend, this is the place to go. As you drive up, the Amarillo area is incredibly flat, so flat that you are a bit worried that maybe you made a mistake. Then, when you get to the part you see the second largest canyon in the country.
