Five layers. That's all Robin Truesdale said he would need to make it through the night Sunday.

"I spent 11 years in Wisconsin. I can pretty much handle it," Truesdale said. "I'd rather sleep outside where the air is fresh and clean."

Temperatures were expected to fall into the 20s Sunday night, forcing many of the city's homeless residents to seek shelter at Haven for Hope.

"We encourage as many people to come indoors as we can, but it's still a choice," said Evita Morin, associate vice president of Transformational Services at Haven for Hope. "We still have people who choose to sleep outdoors because that's what they've done their whole lives and we're OK with that."

Morin said the shelter has seen 400 to 500 people come in over the last few nights. She said those who decide to stay outdoors will have someone looking out for them.

"We do monitor them with 24-hour security. We make sure they have plenty of blankets and the appropriate amount of coats and things like that so they stay warm throughout the night," Morin said.

Bob Stuby planned to be at Haven for Hope when the shelter opened its doors, but he's ready to sleep outside if he has to.

"The concrete is cold and other than that when the wind starts rising up you just try to hunker down on something that will block the wind," Stuby said.

Morin said the shelter had enough room to hold approximately 700 people and it's unlikely anyone would be turned away because of space issues.

"We have not yet run out of room because we open up all of our indoor facilities," Morin said. "We have many acres on campus that can accommodate the extra load."
