There is a one of the liquor stores there has some brewing supplies.. i think it is the chucks off of 31 going north (if i remember right) near I65 and the corvette museum (i think there is a peurtos close also, but those are everywhere..) hope that helps..
I went to WKU, and now live near nashville, if you want to make the 45 min drive, there is a decent size homebrew store here... all seasons is the name.. off of 8th ave.
