You pull out onto US‑1 as the Atlantic and Gulf each catch the light differently—blue on one side, green on the other—while the road narrows and the sea feels closer than usual. The Seven Mile Bridge looms ahead: seven miles of straight asphalt and open horizon that make driving itself feel like an element of the trip.
