Bob, my GW Michigan City does have a grey tint to it with a lot of white "foam" throughout the mixture of blue/green. Daniel, it has green felt that does not come to the edges on the bottom. To answer your question Greg, there are 4 GWs(Michigan City, Barnegat, New London Ledge and Minot's Ledge). The green water on the Michigan City is the one with the blue/green splotches with grey and white throughout the water. The others basically have a dark green coloring all throught the water. And then there's my one other oddball New London Ledge with teal water. Kim says it was the artist's doing their thing when I asked how did that happen.
