Took the boat out yesterday for a run to clean out the engine. As I approached the Garcon PT. Bridge from the west I noticed a barge several miles to the east of the bridge. I did not go all the way to the barge, however, it looked like there was light colored material on the barge. It is not usual to see a barge a mile or two off the south shoreline. Does anyone know what was going on? Were they possibly seeding some new reefs?
