What school was unexpectedly your least favorite when you visited?

UW-Madison. I had heard all my life what a great college town Madison is but when my son was admitted we flew there so he could check it out. I found the city itself unattractive and most of the campus buildings as well except for a small area with older historic buildings on or near the hill. Geographically I found it uninspiring–no mountains, no ocean. It was mid April and the weather was…cold, and still snowing. I thought after a year it might feel claustrophobic once you had walked up and down State Street a few hundred times. My kid loved it, although ended up going somewhere else.
