The Presidio occupies a lot of valuable real estate... maybe sell some of it and down-size?
It should be brought back as an Army post.
It was a beautiful locale for the Army to occupy and having actual sane American military there provided a polarity to the loony leftists who turned SF into an anti-American trash pit.
I recall visiting San Francisco almost thirty years ago on our way to Hawaii.
We stayed a couple nights at Giradelli Square.
I thought back then that the US could pay off our $3 Trillion National Debt if they had sold off the Presidio back then.
This was back when a townhouse next to where Joe and Marilyn had lived was worth the sky high price of $400K or more.
The Federal government owns waterfront property up and down both US coasts and islands like Hawaii that is literally worth trillions of dollars.
Sell it.
Pay down the debt.
