Here's a video I shot riding through part of "the route" in Bay St Louis today. We got very lucky, and got a spot in a highly visible and heavily trafficked area on the Bay, that you normally would have to park a vehicle as a place keeper the night before to get.
I drove in on Beach Road, and a guy with a white 66 421 Tripower GTO came up to us and said they were moving their car from normal "parallel parked" position to the "angled" show position and asked if we wanted to park next to him, so we did!
We walked through the venue, chatted with friends and a few people we didn't know about their cars, and then decided to head to the farthest away coastal venue, Ocean Springs MS. That town is always crowded it seems, and is loaded with some of the biggest, oldest oak trees you have ever seen. When I got to the "main show street" in Ocean Springs, it was SO packed with pedestrians I decided not to drive through. It would have been an uncomfortable cruise because of inherent danger, with so many people oblivious to the cars driving through, and it was around 12:30 and we had The Shed BBQ lined up for the all encompassing meal of the day.
Anyway, the video starts from the spot I parked at, and goes most of the way through the 2 main roads where people park to show their cars. The people walking in the streets in this video are about 1/4 as many as the throngs who were saturating Ocean Springs.
It's nothing special, but it should give you an idea of what Bay St Louis looked like today.
