I found it on Google maps and all 4 of the other major map sites. Searched Point Washington, Santa Rosa beach and a few other names I found on the maps. Came up short on each search though. Something military I assume since the is no indication I could find. We might never know short of driving up to the site (which I assume has a gate somewhere) and asking what is going on or going into town, find the local VFW post and asking.
