Can you tell me what bus to catch from Altadena to downtown LA ?   You can catch the 486 .   That bus goes all the way to LA ?   I believe so .   Is the bus ride long ?   It only takes 45 minutes to an hour .   That's all ?   It's a pretty short trip .   Is there always a lot of people on that bus ?   It only gets crowded once it gets to LA .   Oh okay , thank you .   No problem .
