We have enjoyed riding metros in Mexico City and Guadalajara, and everywhere more prosperous where we have been, and were eager to try out the LA metro last February. NEVER AGAIN!
The smell alone is sufficient, but the headways, good lord. Spotted several sets of foreign tourists just as astoundingly bewildered as we were.
So we rode buses. Good god. Never again. Sorry LA. You suck. No, I don't enjoy driving in LA gridlock (done it many times). What an apex cultural disaster.
I have to admit the transit was really cheap. I'd pay double for Paris's transit in a heartbeat.
