Sorry I missed your survey timing. I noticed a buoy missing and reported it to the Marine Patrol about 3 weeks ago. I beleive it was a black buoy on the north side of Sandy Island (right off the shore of Sandy Island as it faces Long Island). It appears on the Bizer chart but I've been past there several times and don't see it. There are two on the chart along that side of the island but I only see one in the water.
Anyway, just sharing that info. Sorry I don't have a more specific description as I write this. The Marine Patrol never got back to me and I haven't been up that way since the day I reported it so I haven't been able to confirm whether I'm crazy or . . . crazy observant.
