This sounds even better, but can you park there all night?
Actually your not allowed to park in the boat ramp lot with out a trailer, but I've never been hassled. You park along the highway, or in front of the pool. There's always cars parked there for a few weeks while guys are deployed from anfib base. Bring a hose for the wash down. It's about a mile to the bridge, lots of boat docks, or the flats south of the bridge are all good spots
