This doesn't happen too often. When it does it's worth a photo. Not a bad shot for a cameraphone.
Other news: we're potty training and this weekend lucy let us know, in the middle of eisenhower tunnel, that she had to pee. At the other end we grabbed the sesame-street-toilet-seat insert for her, nikki held that above ground and lucy proceeded to pee. It was a serious success considering it was a snowy cold night at ~9,000 feet above sea level at 8pm.
