Consider writing about:
A land swap deal that the Trump administration may be teeing up for Yosemite National Park; what area such a swap could entail; type of development reportedly being proposed as part of the transaction; approval that would need to be secured and/or applicable laws or authority under which such a transaction could take place; how unusual this type of transaction would be for a national park; potential legal challenges to any such proposal; whether this reported plan could be a sign of other private development plans ahead for other national parks.
