Had to fix the title
Gary Anderson (Former Steelers kicker) once spoke at my elementary school I think he was supposed to stay and sign autographs for kids aftewards, but bailed.
Jose Guillen (Former MLB outfielder who started his career in Pittsburgh) once had an autograph signing session at Giant Eagle grocery store in my neighborhood and I got a baseball signed.
Also met and got autographs from a couple NASCAR drivers. My mom got tickets to the 2004 Sharpie 500 at Bristol as a college graduation present for me through her boss at the time who was the attorney for Chip Ganassi and as part of the ticket package, we got to sit in the Ganassi Racing hospitality tent pre-race and I got Casey Mears' autograph. Another time the hauler for the #12 ford of Penske Racing (then driven by Sam Hornisch Jr.) stopped in Pittsburgh and Hornisch was signing autographs.
My aunt and uncle lived next door to Kordell Stewart for a few years, though I never met him. My cousins who were little at the time did try to sell him a sno cone they made with their toy sno cone maker.
