Blair pre-college students and their parents are invited to a Halloween open house on Oct. 29, from 4-6 in the music library. Wear you Halloween costume, play a game of putt-putt, snack on some Halloween treats, and check out resources that are available in the music library. New this year is our book carts that will be decked out for Halloween courtesy of Sigma Alpha Iota, an International Music Fraternity for Women.
