Talking about transportation

You are not familiar with the city, and could not utilize transportation effectively.

A:	여기 어떻게 오셨어요?
B:	. . .~어서/아서 . . . 타고 왔는데요. (Why are you asking? What is your concern?)
A:	. . .-은/는 . . . ~(으)ㄴ데/는데, . . .-이/가 . . . ~어서/아서 편해요. 다음에는 . . .-을/를 타세요.

택시: fast, taking you directly to the place, but not much around in Bloomington
버스: cheap, but does not come by often (자주 안 다녀요)
자전거: You can use it for exercise (운동이 돼요), but it takes too long (오래 걸려요), and dangerous (위험해요).
