My middle kid has received a lot of info from St. John's (they have a MD campus too, in case you are on the East Coast). While I think she would love the intellectual aspect, I don't think she could attend a school without varsity sports (and that touts their intercollegiate croquet team).

There are lots of great LACs in the NE part of the country. They might have your kid's people Amylou - check out the list of top LACs on College Confidential.
