Bump for more closures through the end of summer -- it's now only open from 6 AM to 3 PM, as I found out yesterday afternoon when I arrived at the vehicular gates closed plus chain link sections behind them plus the cheap wooden slat-and-wire fencing filling between the road and golf course and the water's edge.
At least I have some afternoons free now & then, and I might be able to get in some road time in the morning before I have to be at work (depending on the day, of course).
