Northern Michigan University Athletics will participate in the annual Rock the Socks campaign coordinated by Marquette Alternative High School (MAHS). Fans are encouraged to bring new infant, youth or adult socks to the Dec. 9 hockey game between the Wildcats and Alabama-Huntsville. K-12 students can get into the game free by donating a pair of socks. MAHS has also placed collection boxes at the NMU Athletics office, Marquette County high schools and other locations.
