If I had to guess (which is never safe) Id say he parked in the small gravel area on the side opposite Smorgan Steel and then walked to the water. I used to always walk over the RR tracks, go down the rockpile and fish the corner. Casting out into the channel we would always catch horses croaker (bycatch), black drum, puppies and even a sheepie every now and then. Not trying to burn spots, but that is how we used to always shore fish the Gilmy..
