Great. I'm going to go out and get started NOW. Funny you mention concrete- I was just going to ask about whether there was anything wrong with using a bunch of concrete, since I have a ready supply from a big pile of blocks, etc. near a local site. Picked up a bunch today. Won't be able to line a shore with it....not near enough....would be complicated....but I can sure use it to provide depth/mass to the extension of the rock pile. It will really come in handy. Plus I like the idea of the cinder block-style ones, as I can see the little guys hiding in there (talking the smaller openings; obviously 6" openings aren't too much protection.)
