CHICAGO (CBS) — A hearty and determined band of college students who are military veterans camped for 24 hours in these frigid temperatures to raise money and awareness about the problem of homelessness among veterans.

The Columbia College student veterans said it was worth enduring a full day and night of single digit and below zero wind chills.

“Veterans are more at risk of becoming homeless than the average citizen,” said Marine Matt Patruno, who is majoring in arts and entertainment management.
