PALO DURO LONGHORN

On one of my road trips I visited Palo Duro Canyon State Park. When it was time to leave the park, I stopped to visit a group of longhorns grazing in a field. It had been such a whirl wind day I really needed a minute to gather my thoughts before I returned home. Looking around, I appeared to be the last person in the park. I saw no people and no cars, just me and my long horned friends. I wondered if I should lock the gates as I left??
