I lived at home because it was cheaper (free other than yard work, housework, and doing my own laundry), campus was 3 or 4 miles away depending on which end I needed (and roads were just dangerous enough I wasn't going to cycle, tried it, didn't like the assholes throwing shit at me). Most students lived on campus, but many (including locals like me) lived off campus.

But even those who lived on campus, the furthest dorms were where I'd have had to park on those mentioned days. I did that sometimes, but it really was a 20- to 30-minute walk depending on where I was going on campus because they decided a mile long parking lot made more sense than a parking deck (later built, after I graduated).

Also it had a bus service, but it really only covered connecting the business school, psychology school, and main campus. The massive parking lot was not covered by the bus service, which didn't make sense.
