I think you can find all the types you want to find in any top MBA program. When I visited Tuck, it certainly wasn't hippie-ville, and when I went to Columbia, it certainly wasn't quant-central.
One guy at Tuck, and this guy was a Columbian international student representative at our lunch, did remark that the hot girls were few and far between.. I thought that was humorous - at the same time it shows how open and honest that society is. cons and pros, respectively...

I guess we'll wait and see a few more days.. I wish they would just publish the decisions online on a pre-determined day....
