I watched the videos of the meetings where the changes were discussed. TWRA conducted focus groups and at least 2 rounds of surveys. They said that the majority of comments they received indicated hunters wanted the same seasons statewide (stop start), they didn't want the private lands antlerless hunt, they wanted muzzleloader season brought back in CWD counties, and they wanted CWD counties to end with the rest of the state (not end of January).
So to "simplify" they eliminated Zone CWD and made the same seasons across the state, but with different management limits by zones.
