Looks like RT 399, along the barrier island! We lived in Navarre Beach, east of P-cola.

It's the road to Fort Pickens across the bay from Pensacola NAS. Will be back there in the end of January 2014 for 2 weeks then off to Biloxi Mississippi for 2 more weeks.

I thought I recognized this picture. We camped their in April this year (2014). Loved it! Beautiful! Area A has the best sites that are closest to the ocean. We will go back in 2015.
