One advantage I have riding at night in the morning is the traffic isn't bad at all. Hardly any at all. So the wife takes comfort in that. But I still call home every morning when I get to work to let them know I'm OK. I give them three or four ringy-dingys on the phone. And if I forget one day, she's calling me right away to make sure I'm not laying in a ditch somewhere.
