public transportation

i have been here now for a month, its kind of crazy! just when we think that we have the public transportation down.. well we don't. yesterday was our day off so after work we thought we would go to the mall. instead of taking us 20 min to get there it took us an hour an half, because we took the wrong bus lol. once we got to the mall we had a good time... but then on the way back we took the wrong bus again! lol but we didn't know that there were two 3422 buses. the nice bus driver finally helped us after he noticed that these crazy americans didn't know what they were doing. to sum it up... we spent more time on the bus then we did at the mall!
