Is your son looking to live at home, and that is why you mention community colleges in Oak Creek? Because MATC is the only one with a baseball program right in your town.
However, Madison MATC plays a very competitive schedule, and traveling time for him to Madison may be close to an hour, but is still doable.
There are other JUCO's in Wisconsin and IL that are close enough to drive daily.
If you are looking for more personal advice, feel free to leave me a PM and I can help you out.
Our son also played a lot of traveling and competitive ball, and started out at a JUCO, and has now transferred to a 4 year university. So, I've got lots of experience in looking at different schools, and know some of the programs out there, especially in WI and IL.
I'm wondering, also, why the high school coach or some of your son's traveling coaches haven't helped you out in this regard.
