Minnesota, Iowa, Missouri, Arkansas, Louisiana. A whole pile that don't have huntable populations of elk and Texas, which has game that's unavailable to most people.
Now those states might have a tiny population tucked away in some corner, but that doesn't really count for anything. Along with states I know have them but tags are almost impossible to get and are impossible for non-residents. No NR elk tags in SD, does NE, KS, or OK have nonresident elk tags? ND?
There are really only eight states that have populations of huntable elk. I get there are elk elsewhere and with lottery ticket odds you might get a tag, but there are really 8 serious destinations for elk hunters.
