I don't know anything about Sewanee's current state of athletics, but as a former student there, I wanted to clarify a couple of things that quillgirl said, most of which were right on the mark.
Sewanee is about 45 minutes from Chatanooga and 1 1/2 hours from Nashville. It definitely has a rural feel.
Regarding the comment that Sewanee "is not a party school," maybe times have changed, but it was a HUGE party school on the weekends with lots of drinking in the 1980s when I attended because basically, there wasn't a lot else to do there after classes were done (besides study and hike, unless you were an athlete). In fact, the school had (and perhaps still does have) 3 university-sanctioned Party Weekends, where classes actually shut down for a couple of days and fraternities and sororities hold numerous social events (all through the day and night) for a 4 or 5-day period. When I attended, there was a LOT of alcohol consumed at these parties.
