"THE WORST FORM OF INEQUALITY IS TO TRY TO MAKE UNEQUAL THINGS EQUAL". (Aristotle) Today was the same as yesterday, just 45 degrees different. Angle not temperature. Today we rode due east with a strong south wind. Yesterday's riding was due northeast with that same south wind. So, today was a sterner ride than yesterday. The route shadowed Rt. 40 using south and north frontage roads which at times were old route 66. I had the second flat tire of the trip. We passed center pivot irrigated fields of cotton and corn. There were many wind mills as well. Shamrock is located on the eastern pan handle of Texas. It was named after the lucky Irish shamrock by the first postal clerk. The "U-Drop Inn" of Rt. 66 days has been refurbished as the town historical and information center and was featured in the movie "Cars". Tomorrow we leave Texas (our fourth state) and enter Oklahoma, our fifth state.
