Moats.

Australia has it right.  Hawaii has it right.  The 17th green at TPC Sawgrass has it right. Japan has it right.  Granted 75% of the entities mentioned here did nothing to get it right, they are just islands.

But I don't see them as islands.  I see them as plots of land protected by the best defense ever...the moat.

Herstmonceux Castle, Sussex, Rebuilt in 1777

You see that moat? Please explain to me how, in 1441, when this castle was originally built, the Department of Landscaping and Defence (as spelled in Sussex) knew the effectiveness and overall badassness of moats, but we don't use them now.  It is 2010 for some type of allegedly destiny controlling, omnipresent entity's sake, why are we not using moats?  It is a simple defense, here are some key elements:

• some type of large, deep ditch filled with water, preferably SmartWater, because that will create a SmartMoat...I don't think I even need to tell the potential damage a SmartMoat could do.  
• various occupants of the moat include, but are not limited to (Note: all occupants of the moat shall be enhanced by SmartWater when applicable):
• alligators...the traditional choice
• water moccosins
• battleship and patrol boat located at D4-D8 and H10-H11, respectively
• piranhas
• frickin sharks with frickin laser beams attached to their heads
• dudes with gold chains and AK-47s riding jet skis (imported directly from an episode of A-Team)
• portugese man of wars
• free style rapping clones of michael phelps
• a draw bridge...I realize that Australia does not have a draw bridge.  But, it has kangaroos and dingos and whatnot, so the drawbridge requirement can be waived.

If moats were not the bees knees, why would there be a professional football player named after them?

What people don't realize is that Ryan Moats comes from a long line of Moats.  His ancestors worked primarily in personal security....

Tom out.
