I was born in Casper and although I wasn't raised here, I've been in Wyoming long enough now that I should know about the majority of food traditions. It appears a big one has escaped me.
We believe that no one in their right mind would ever want to leave Wyoming. But, let's face it, we're not exactly objective. There are scientific numbers that prove it is true that a very small percentage of people want to leave after they're here.
Here in the Cowboy State, I don't think we have our own distinct accent, so to speak, but we do have a tendency to pronounce words a little differently than other regions.
