How can you even think of selling our heritage? Yellowstone, our 1st NP was dedicated "For the Benefit and Enjoyment of the People" and this applies to every National Park after it. I live in the backyard of Yellowstone and Grand Teton Parks. I grew up in them. Bryce, Zion, Grand Canyon...we've enjoyed them all. Often. You would sell them? Treachery at its worst. Use the USPS and INFORM every American of what is being attempted by the Biden administration, hoping no one will notice. Ryan Hunt, if you're still on the NPS Board, did you approve or encourage this? Please DO NOT sell OUR national parks.
