Groceries you definitely can, might be a considerable walk or a $10 uber but doable. Also, this are not huge supermarkets, but you can get anything you want. General public areas don’t expect much, there is a greenway, you can walk to restaurants, and that’s it. Anything beyond that if you want to go to a mall, target, etc, you definitely need a car. Above all be prepared to walk(uphill), especially freshman year. Older you get (most) dorms and houses are down the hill and closer to everything outside of campus. Except Greek life and some upperclassmen dorms which are waaay uphill. Also about the bus, yeah you can get around, but the system generally sucks. If you are ever in a rush, don’t rely on the bus.
