My Travel Bugs (1)

Pirate's Gold
I want to sail the seven seas! I want to cruise in your boat, to sail in your ship, to paddle in your canoe or just to sway on inflatable mattress with your girl-friend. Finally, I want to return to my home cache: the Treasure Island at river Danube
This travel bug waits to be released in the wild, if I find suitable cache.
