Shaumburg or Hoffman Estates would certainly be good for me, easy to get to from here! You would probably get more draw from the Milwaukee area with that location too.
Although if the date changes, I may not be able to come, depends on where it moves to. I will keep an eye on this thread because I would love to be able to attend - I did my first SCS shoebox in Madison in January and had such fun! Good luck planning - group events can be so tough with alllllll those details!
