Who knew that vast herds of tongue-wagging, snot-nosed, dust-covered cattle once passed through the Big D on their way to Kansas, where they would be carved into rump roasts and rib eyes? Well, most everybody, but it's easy to forget, because other than the Dallas Cowboys and Western Warehouse, you'd never guess Dallas was once a cow town. Thank the Lord for the Heritage Farmstead Museum in Plano for preserving a bit of the Old West and reminding us that for all its romance, the era kinda sucked. Check out the sheep, the one-room school house, the rusting tractors, the herb garden and the chicken coop. And then get in your car, blast the A/C and thank God that you were born 150 years later.
