The North Campus commute times are pretty optimistic, especially for commuting during business hours.
My son’s on North Campus and he has told me 20-25 minutes. I experienced this for a football game in a very packed bus going to the game and back with him. Really not bad overall and a nice way to meet some people.
I presume these commute times do not count waiting? So it takes 20-25 min after you get on a bus at Bursley/Baits to get to Central?
