here's some pix for you so you get a sense of what i'm talking about and maybe to help you decide between grocery vs something more pannier-like.
for size reference that's a 47 atlantis w/ 26" wheels.
though since you seem to be in college/university the arkel bug might work out better for you since it becomes a backpack. i can say that while it's nice to have the ability to carry the knog around, it's so big it's not really something i'd do for long distances.
i think.. from the back, i sorta look like a giant messenger bag with a head and stubby legs...
