Well constitutionally all national parks and national forests are illegal. The constitution only allows the central government to own 10 square miles around the capital and several seaports. Territories are federal until they become states then they belong to the state and the people. Forts and bases are to be leased from the state and once they are decommissioned they are to be given back to the state with all improvements made to the property left intact. Everything else belongs to the states and the people.
