Hey Rick I was just trying to make it easy for you. I think the fleet would be spread out enough with about 2 miles to sail before the bridge. In the past we all went through at the same time. After all it is the Steeplechase and you can paddle.
If it still necks down and accelerates the current right at the mouth - I would never want to have to race through that. Two years ago, we couldn't get out of each other's way long enough to let anyone get a run ... and we were only trying to get up the creek to the start line (we weren't racing at this point). I can't imagine 30 boats all cramming in there to try and get through.
Here's the video...I can't seem to embed a Daily Motion video.
