The Denver Rescue Mission’s downtown day center has been busy Wednesday, as temperatures hung on in single digits through the morning.

The center opens around 6 a.m., serving breakfast to as many as 800 people, and offering a place to stay out of the cold through the day, before closing at 10 p.m..

"A day like this we are a packed house," said the shelter's Alexxa Gagne. "In our dining room it’s pretty much standing room only if you will, we have our tables maxed out and we have warm coffee for people."

The Rescue Mission’s overnight shelter and an emergency accommodation were at full capacity Tuesday night, hosting more than 600 men. Women, children and families were referred to other places where they can stay.
