It is forty degrees, school is out, and the kids from the next street have a cubby house that is frankly asking for it. Sticker swappers bring in the coins, coins buy bean bag throwers, launcher kids and mates on bikes, and nobody moves until you say so. Hold the line while you build a proper army, then call the charge. Bean bags beat bikes, bikes beat launcher kids, launcher kids beat bean bags, and every kid swapping stickers is a kid not throwing anything. Knock their cubby flat and the next street is waiting, and they have a bouncy castle.
