dont know about that i mean the island resort map. if you are on another map you would know, so otherwise its the island with the hotel and bungalows and lots of empty long streets you can drive through. the old marina is top NW. hard to miss if you head that way
Ok I finally found a spade. It was leaning against the fence at the mechanic's shop in the northern island area (Act1 map). Right at the fence gate entrance to the shop, on the left as you enter (against the barrel).
