Hueski, you should be ok next weekend. Saturday there was no parking except at the causeway, which is the only reason I fished there. When I went earlier this morning the crowd was much thinner. Even when I left around 10 am the was plenty of parking at the lighthouse, pier and only 3 cars on the causeway. Saturday, I guess is just packed. I do not get to visit my old stomping grounds too much any more so I have no idea if the park is always as full as it was Saturday.
Good luck and let us know how things go.
