Don't have time to do a thorough analysis of all arenas in the CCHA
(actually I haven't even been to all of them) but I'll start the
discussion with my picks for best and worst:
 
        Best: Munn Ice Arena @ Michigan St.
              Very nice full bowl arena - very modern, good crowd.
 
        Worst: Yost Arena @ University of Michigan
               Very old, poor sight lines, lots of bad seats
               (especially for visiting fans), crowd is active but
               can appear unfriendly
 
For what it's worth, I would rank Norris Arena @ Lake Superior to be
in the upper half of the CCHA, but not the best.
