@takanuva U Mich was very nice, if you ignored the weather. 
Since this is a UIUC thread I’ll keep it brief. The facilities at U Mich were beautiful - parts of it reminded me of “north of Green”, the BIF and the Ike. Frankly it felt like it had more, not necessarily better “newer construction”. (That said the dorm we visited was not as nice as FAR to my surprise.) Overall it just feels much larger and more spread out within Ann Arbor, the town.
As for the students, they were what I expected…in a lot of ways similar to UIUC. Fortunately, my S felt like he could fit in well there. (I must admit I went in thinking he might feel a little intimidated.)
Anyway, we have 2 more 'admitted student 'campus visits before making a decision - IU (never been there before) and back to UIUC. Time will tell.
