Yeah, I don't mind the extra thumb, it was worth it that one day to ride up in there.

I just realized. I am very familiar with that area from fishing it. If you weren't that area really is a nightmare as Tom said.
There are submerged rocks and all kinds of features barely under the water surface in that area.
Depending on tide height, many of them are lost from sight, but only 3 inches under.
The obvious hazard is the launch, but I have seen worse.
My bad. I wouldn't go out there to ride. If you do, be wary of stuff around the channel markers and about 50 yards offshore, on the other side of the small boat channel.
