Jarts (lawn darts) at rest. We played many hotly contested rounds of this game, but I invariably lost. These fun little toys are now banned in the U.S., which may explain why someone decided to steal four of the darts from the yard one night last week. I knew that they were illegal to buy, but is it really illegal to play Jarts? Game sets appear to be selling for over $100 on iOffer.com and also on eBay—"for display only". Crazy.
