Glad you had a great day on the water.
The canal at the bridge can be very dangeous with minus tides.
People have been thrown out of there boats; boats have flipped over at the mouth of the river. You had a minus 0.9 tide ripping through there and the afternoon tide will be almost a minus 2foot tide. You get two or three 3-4' waves close together. the bow goes down on one wave and the boat dosen't recover quick enough so the next wave grabs you. Your lucky that you weren't thrown against the wooden bulk head. You are fortunate that you haven't had that almost happen before in the last ten years.
Hauled my boat out at 7:30 this morning for the season. Pulled a muscle or whatever in my shoulder while pulling on the transom tye down safty rope. Can't believe that happened. Wasn't doing anything strenoues just pulling on the rope. Was going Bow hunting this week but could hardly lift my arm at the moment.
