Transportation to and from a nearby state school plus food is not free even if your living with your parents. 5$ a day in food * 7 and 15$ a day in gas, maintenance, parking, etc * 5 days = 110$ a week * 16 weeks = 1760$ a semester. I went to a state school and adding a 45 minute commute each way was not worth the ~3-4k /year cost savings.
