Three years there.....
Daytona, Daytona, Daytona.... No opening bridges. You can get stuck in St. Augustine in the inter coastal as in any Hurricane
or National Emergency
the bridges are locked down if you are up in the river area... Daytona has a high fixed bridge until you get past Halifax
Harbor Marina about 10 miles down the Intercoastal. I think the infrastructure is far better in Daytona as well.
Also I went back to both in March and Daytona and Daytona Beach Shores specifically was still quiet, where St. Augustine was a madhouse of Tourists and traffic everywhere...
My 2 cents worth.
