What the proposal said, and what the decision did

No figure from the proposal has been checked against the decision on this fight yet. What the record does hold is the issues ledger below.

The National Park Service is proposing to open about 37 miles of multi-use trails at Mammoth Cave National Park to bicycle use, and it'd also allow horseback riding on a specific 5.4-mile road corridor. This rule would affect visitors, equestrians, cyclists, and park managers who oversee recreation planning. It's a proposed rule, so it's still in the public comment phase before any changes take effect.
