Dallas, Cheyenne, Maverick, it's always funny to see those names used, because nine times out of ten they're used by parents who've never been out West in their lives and whose main view of the West is watching reruns of "Dr. Quinn" or "Walker Texas Ranger."
I propose these people branch out a bit and start using some less common Western names. How's this for size?
Lasso
Pommel
Mustang
Stirrup
Saddle Sores
Cow-Pie
Cactus
