The reason I like to take a subway, That is =is that subway is cheaper than other transportation and faster than ohter =other things. Also That is very correct about time.= and it is always on time. I think that bus and subway are most famous transportations. If I take a bus or taxi, That sometime can't keep the time. Because There is rush hour at 7am , 6pm in korea. At that time , Most of people commutes their company.=commute  to work.
So I almost will get to take a subway before I will buy my car!!!
