No, I have not, if you mean the one on the mainland. Looks like a nice place, not sure what the winters are like there.
I am mostly a Baja sur guy in the winter. We went out sailing for a couple days this week on Bahia de Conception, was good. Backed the little Compact 21 up to the beach and stepped off in 18" water.
The cabin my dad built had an upstairs door about 12 feet above ground level. There were a few winters we walked (skiis) straight in. Dug down to get to the outhouse and front door, but all that snow kept it warm inside once we got the fire going, cleared the stack.
Looks like a series of strong storms heading into the PNW over the next week.
