Hello! I am also 73 and disabled Vet. I live in central Florida now but lived several years in Belle Chase LA. I used to have good luck with Red Fish, trout and flounder in Adam's Bay area and Venice in the passes. If you go close off shore to the old (not active) oil rigs. There is great fishing there for Red Snapper, Triple Tail, Black drum and cobra to name a few. I loved living and fishing in South Louisiana. Much better than Florida.
