Measuring the Bridge

According to the charts, the bridge is supposed to have 65 feet of clearance at mean low tide. What the heck does that even mean? In any event, we have learned while trucking that not all clearances are to be trusted. We also wanted to run some old gas out of the dinghy tank. We also wanted to check out some dolphins. So we did Dinghy Dolphin Discovery Day. We saw a bridge, birds, fishermen, and yes, three dolphins! No video on the dolphins, though.
