I cannot believe the size of this tarp! It covers the house! I had no idea they made tarps of this size or magnitude. What kind of construction are they doing that it has to be hidden? Maybe they're hiding spies on a stakeout! Perhaps this is a house full of stolen goods? Or maybe the constuction workers just like to play Wii when nobody is looking.
It's probably protection from all the rain we've been having, but it's more fun to imagine that something weird is going on.
