Jeff Suess at SF Rec and Parks oversees the licensing of Parks properties to private operators, including the GGP Carrousel. (This unusual spelling is the official one, I’ve learned.)
He gave me contact info for the people who run the carousel, as well as the engineer who restored it back in 1998, and who is based in the area (Hayward).
I emailed the carousel operators in order to run the idea past them of getting an estimate for how much fixing the organ would cost, and then if it’s reasonable, doing a local community fundraising / crowdfunding campaign to make it happen. They like the idea, and we hope to meet in a few weeks to discuss. Yay, fun!
