Lake Markers

[MeEscape]

Some time ago someone posted an attached file which was a simple circle, half black, half red, with N,E,S,W printed on it indicating the passing direction. I've searched but was unable to locate this post, if that someone or someone else remembers what I'm referring to, could they repost it or redirect me to the file? It was a good simple aid for folks that don't drive often on the Lake.

Thanks in advance.
