When we lived in So. California, the traffic was so bad that my husband would go into work super early (3:30 or 4:00 AM) to avoid the traffic and then nap in the car.... but not running. (Corona to Anaheim commute) Brought blankets in the winter and opened the window in the summer. He worked shifts, so couldn't start/leave early. Traffic is crazy in So Cal, so glad we moved...
