Kind of caught this thread late. I'd imagine someone will take over The Point due to the location. My family goes all the way back in the Delta, as one of my great-grandfathers was very involved in its construction as we know it today. That is, the erection of levees and creation of the "islands". My father's cousin's family still operates a farm on Ryer Island, where I spent a lot of time pheasant and goose hunting and just hanging around in my youth. As did my Dad, there and other family farms. One of the funnest things I've done in boating was taking my Dad cruising about 7 years ago on the Delta, seeing all the old spots from the water, hearing him talk about those same spots in the 20's and 30's. He kind of liked what modern times had brought, particularly more places to dock, more restaurants on the water, better navigation aids and bridges. Before radar, they had big sounding boards erected at critical junctions and shoals, and more bell buoys and fog horns, quite a racket when the tule fog set in.
Since it is all in my blood I do miss it, including some "misty" afternoons at The Point. Luckily from my personal perspective as a Delta Rat, I died and went to heaven when I started cruising the Intracoastal and adjunct waterways in South Carolina and Georgia. Look at it this way, if California stays in decline, the Delta will stay closer to its roots for longer. There's your cloud's silver lining!
