Not only everything about Sioux sports, but Kalker also knows all about GF HS athletics.
He is like Rainman. He might not be able to tie his own shoes (velcro), but he could tell you who won the 1976 ND State HS Football champs, what the score was, and how many yards the running back had for the winning team.
My two favorite Kalk and Gretzky stories:
When they biked out to the airport in below 0 temps to greet the national champ Sioux hockey team when their flight came in.
When the Boys Ranch came to Kalk's house for donations and Gretzky gave them Kalk's TV, so Kalk duct taped Gretzky to a chair.
