Under the proposed new rule, the ban would be lifted only in national parks and wildlife refuges located in states that permit concealed weapons in their own state parks.
Although 48 states have enacted concealed gun permit procedures, only 24 of them currently allow concealed guns in state parks.
Those states are: Alaska, Arizona, Arkansas, Colorado, Connecticut, Florida, Indiana, Kansas, Massachusetts, Michigan, Minnesota, Missouri, Montana, Nebraska, Nevada, New Hampshire, Ohio, Oregon, South Carolina, Utah, Vermont, Virginia, Washington, and Wyoming.
