Yep, They did not mark the one right past the no wake zone sign(and that is a bad one) , but they put a marker right in the middle a little more downstream at a point I have never had any problem with.
I was kinda like

too when I saw them. And GPS #'s ain't gonna help ya as you can be just a few feet off and hit it. Just remember as you take the curve to the left after the no wake end sign, stay to the right of the bend and you will be fine. This is assuming you aint trying to go out on a negative tide...
The ones out near the mouth are kinda ok, as you can stay between them and be alright.
I made this up one time and will repost it....

The more I know about something, the more I know that I did not know as much as I thought I knew that I knew.
