my kids play this weird game when we are on the road called, "the evil witch" and it is actually quite clever. the car directly behind us is the evil witch and as it gets closer the kids start yelping and carrying on telling us to hurry or to go faster. if the car passes us, though - that's it. she ate them.
bryce says he came up with the game and i love hearing them play it. i would definitely prefer for a different character...say, like a mean lion or something, but no matter. it's a good old fashion made-up game between brothers. and those are the ones you remember forever.
