"you live in california and wonder why we need a car? the public transoportaion system is the worst in the country! maybe even the northern hemisphere! "

My family has 3 young kids: 6, 9 and 11 years old.
They really wanted to ride a train so last winter we rode the next similar thing, Atlanta's transport rail MARTA into the city on a Saturday afternoon. It was the first time any of us rode.
First part of the trip went fine, but on the way back some drunk in the front started yelling obscenities to the other bum in the back.
There we were captive for a time in this awful situation.
At least no one got stabbed or shot......
