Just saw that they are starting to put up info for the 2012 Wisconsin coaching clinic. Been to it the last couple years and it has been really good. Many, many different sessions (12 sessions at a time), good speakers (HS, college, pro), well organized, etc. They are just starting to put stuff up, so I am sure there will be more to follow. It is in Milwaukee, so probably a stretch for those of you in central/western iowa, but for those of us on the east side, it is an option worth looking at.
