Matusalem,
Just a thought here when I saw the water in the backyard. Dig out the backyard put in a giant pond with islands, reefs, ports, maybe even some sharks with laser beams attached to there heads (Oops wrong movie), and such, then add scaled down remote controlled sailing ships with small cannons and have sea battles. What say ye?

P.S. okay how about some evil tempered seabass instead?
