Clifford K: I think technically cycling to college is safer than cycling to college. I know shortcuts so I don't have to ride through intersections/roundabouts but the route to Uni there's no way you can avoid them. So bassically cycling to Uni is more dangerous than college.
I don't know how it works with the spare locks although at college if you use their locks you have to ask the staff for the key I think. (same for bro's uni as well).
Hardrock 23: good point
