"TIRE CHAINS REQUIRED" flashed on the emergency highway sign as I began to ascend Wolf Creek Pass. Powered by a Cummins diesel engine, the flatbed pickup truck easily yanked around the 20 foot gooseneck trailer filled with Corriente cattle I had just purchased outside of Trinidad. Andy kept me company in the front seat while Hugo, my red heeler, excitedly paced non-stop from side to side on the flatbed intently watching for oncoming semi's to snap at as they passed. The weather was calm with pleasant temperatures so Andy and I assumed the sign's warning was accidentally turned on.
