Thinking of stopping, rather than driving past, Ann Arbor for a break from driving back to Madison, Wisconsin. This would be for an hour or two tops. Not interested in touristy things. Is there a particularly authentic area that would be fun for window shopping some local stores (NOT chain stores) and maybe a light lunch/snack/coffee? Checking the boards it sounds like Kerrytown and Main Street might be good, but then there are folks who claim they are not what they are cracked up to be. Maybe a walk through campus? I dunno. Thoughts or advise? Thanks in advance.
