You should have it in Marquette. Not many other than the very eastern UP folks will go if it is below the bridge. You have it in Marquette you will get the Northern WI and All of the UP there. My .02c. Then again I am bias because I don't like going below the bridge........ sorry.
Would be nice to have. Maybe talk to the WIFMX guys and see if they will put on a show to bring more of a crowd. I'm sure there would be plenty of vendors that would be game for something like that.
