Interestingly enough, the following school year, I would transfer to what then was called the Minnesota Center for Arts Education (now called the Perpich Center for Arts Education), aka the Arts High School in Golden Valley (it's at the old Golden Valley Lutheran College campus), and heard all about the blizzard from students who were enrolled there at the time.
Being a residential high school, students were literally trapped on campus without food service. The dorm staff had to scrounge up food for the students in the dorm. The only restaurant nearby was a Denny's that was across Olson Memorial Hwy (Hwy 55) from the school and those students who braved the hike across 55 had limited options at Denny's.
