Loudon is about 20 minutes southwest of Knoxville. Just down 75.
There isn't much to do in Loudon, per se, but there is plenty of stuff in Knoxville. Free concerts on Thursday in downtown Knoxville, and plenty of bars and what have you. University of Tennessee is in Knoxville, and it has a fine selection of good looking women. Blue Cats, in downtown knoxville, has a pretty good concert calendar generally. Might be able to catch some bands.
I know there are some golf courses in Loudon.
