I used to live in Wrightsville Beach, NCand gigged in that area. I'm in Destin now and we don't have those 4'-6' tides like you do. Our tides vary by less than a foot most of the time and we only have one high and one low a day (except for 2 days a month), where you have two highs and lows every day.I think it's harder to gig in your area and has to be planned better in my experience. We always planned to start gigging there when the tide justbegan coming in. We would start closer to the inlet (called passes down here) and let the incoming current push us along with it. As the tide began rising the flounder would move right into water only a few inches deep sometimes, but as soon as it began falling theymoved to deep water immediately and gigging was over. We rarely got any there on a falling tide and stopped trying after the tide changed. Down herethe tide rising or falling does not seem to make as much of a difference, as I think it does in your area.
