A1A, Daytona to Fernandina (and the Mayport Ferry) is one of the nicest relaxation rides in this area. Sun from Daytona to Mayport and shade from Mayport to Fernandina. Good eats all along the way. I think there's a fort (from the 1500's Fort Caroline in Jax to the 1700's Castillo de San Marco in St. Augustine) every 50 miles or so that make for interesting history breaks.
