Where are some good spots to wade fish in Grand Isle in the middle of May?

Elmer's island; anywhere behind the breakwaters

Elmer's Island is good because you can drive up and down the beach and fish multiple spots in a short amount of time. You can also cross the bridge over Caminada Pass and about halfway down the island there will be rock piles running parallel to the island. The fish should be moving out into the surf now, but the numbers won't be there yet. Another spot is the State Park at the end of the island. I don't think the marinas have live shrimp yet but they do have cocahoes and croakers. A plastic shrimp under a cork still should work pretty good.
