tons of grat music and music shops, Bass Pro Shops has a HUGE store near the intersection of 40 and 66. Also the minor league baseball stadium is across the street.
How old are the kids? There are LOTS of flowers in bloom at the higher elevations. There is also some pretty good trout fishing around there.
on the Townsend side of the mountain, you can rent tubes and float down the Little River. Or spend a few hours swimming and jumping off the cliff at the 'Y'. (pm for more information)
regishay mentioned the Smoky Mtn Brewery, if you enjoy a nicely crafted microbrew....by all means check this place out. There are several restaraunts in the Knoxville/PF/GTLNBRG are that carry these beers. The Blackbear is outstanding, the Pale Ale is pretty good, and be sure to try the seasonal. I take a couple of jugs of this beer home to the family and a few select friends whenever I make the trip back to MS. This place is as family friendly as a brew bar geets.
