Jack In The Box is the other reason, IMO.
Jack used to be the worst of the worst. Now they are very, very good.
We have Jack in the Box in Pocatello. I have to drive about 60 miles west to Burley to find a Carl's Jr. Frankly, the Black Angus burgers at Arctic Circle taste just as good as any burger I've had at Carl's and we have two stores in town. Their shakes are outstanding.
My wife and son joined me for a brief ride around town last night on our motorcycles. We stopped by Sonic to get a drink. We have so many choices in town. McDonald's, Arby's, Jack in the Box, Wendy's, Sonic, Arctic Circle, Central Park, Tastee Treat, Quizno's, Subway, Schlotzky's, Jimmy John's, Taco Time, Taco Bell, Burger King and Dairy Queen. That's just the fast food joints. Sitdown's include Chile's, Applebee's, Texas Roadhouse, Ruby Tuesday, IHOP, Perkin's, Red Lobster, Denny's, Pizza Hut, Golden Corral, Winger's and Sizzler. That's the big chains. Locals include Chang's (chinese), ButterBurrs and Uncle Jim's, Tom's (greek), Grecian Key (greek), Riverwalk Thai (in Lava Hot Springs), Puerto Vallarta (mexican), Mandarin House, Taste of India (Indian & Nepalese), Remo's (steak & Italian), Buddy's (italian and great salads) and Elmers. We even have a micro-brewery (Portneuf brewing).
What are we missing? Vietnamese and German cuisine. Idaho Falls has lots of sushi bars, a TGI Friday's, Red Robin and some sports bars. If you can't find it in Pocatello, it's probably available 50 miles north in Idaho Falls. At 75 MPH, that goes pretty fast.
Jack is in Texas along with many other states.
