I fished Grand Isle on Friday and Sunday.
Friday I went with my buddies Mark, Kerry and Brandon in Mark's boat. We started out in Caminada Bay but couldn't get on a good bite. We made a move and hit the east end of Grand Terre. There were birds and bait everywhere behind the breakers. We caught keeper trout on just about every cast, until some potlicker rolled up on us and blew through our fish.

We never could get them restarted. We ended Friday with 50 trout, one big redfish and more sail cats than we cared to count.
Sunday I went out solo. I guess my buddies didn't like the idea of fishing right after Bonnie. I went right back to Grand Terre, but the sail cats must have cleaned house because there wasn't any trout to be found. I moved farther to the east past 4 Bayou Pass and found the trout in a feeding frenzy. They were going nutz on schools of glass minnows. I quickly got my 25 trout and played catch and release for about an hour afterwards.
Here's a link to a video I took on my phone of the trout busting glass minnows.
