Is that bad the situation in Florida??!!
Worse.
Dan,
I'd look to the medieval times for your solution. First, dig a deep moat around the rib and place a few hungry everglades gators to prowl around the structure. Construct a European-style fortress equipped with guard towers 100 feet high and walls 30' thick. I would go over to Port Everglades and ask the ship yard for scrap molten metal, which you can heat into liquid and pour over the invading marauders. If the walls are breached, set up a line of defense with your dogs and family with powerful cross bows, which you can purchase from Gander Mountain. Make sure you have a large stock pile of baked beans and sweat peas cans in case of a long seige. Oh yeah, I almost forgot, a quality hitch lock can go a long way.:D Be strong!
