Besides BART, MUNI is the other means of transportation I often use especially in the summer months when I am on vacation and do not commute out of the city of San Francisco. I have lived here nearly 25 years but I have yet to travel on all its lines.

Marc and I took a MUNI train today to go to Union Square and the train was totally empty and quiet. This was definitely a rare occasion. Most of the time, it's standing room only in these trains especially during peak hours.
