University students are spending the week sleeping outside to raise awareness of homelessness.

A small group from Concordia University enjoyed the night in the storm -- by using their signs to slide down the sidewalk on Mackay St.

They're being joined by students from McGill and HEC Montreal as well as members of Projet Montreal.

On this fourth day of their campaign Concordia has raised more than $11 thousand for Dans La Rue and Chez Doris.
