Speaking of distance...why are Colorado, Utah, Wyoming in midwest breakout? Have you ever driven across Nebraska? You guys might want to look at a map again and maybe redistrict a bit.
A more logical Western (Southwestern) group might be Colorado, Utah, Arizona, New Mexico, Texas, Nevada, California, Wyoming. Just a quick example...Denver to LA is a relaxed 16 hour drive. Denver to San Diego is a relaxed 17 hour drive. Denver to Las Vegas is an 11.5 hour run. Denver to Santa Fe is about 8 hours. Denver to Phoenix is a bit of a run, but it isn't too bad, either. Denver to Cheyenne is a stroll in the park. I know that Greenwood is close to Indianapolis as I have been to both....but the odds of driving that far are pretty remote. I think you need to redistrict the regions a bit. It might spark some interest.
