Nizzy, Dkramer and I did one yak dive today from the county park north of Sharkey's.Viz was about 10-15 @20 FSW, water temp was 66-68F. No significant tooth finds to report. The barge working off the beach hauling the limestone blocks for the breakwater/abatement/artificial reef project is now working south of Sharkey's pier, but hauling from inside the jetties and shows little or no regard for dive flags. I witnessed it pass dangerously close to 4 dive flags, not to mention Dkramer's yak flying a dive flag.
