It’s not the time of year to be sleeping outside.With temperatures already dropping to single digits once this winter, a men’s shelter named Lighthouse Full Circle has been a vital lifeline for a number of homeless Warren County residents.“It’s sure better than sleeping under a bridge out there in the cold,” said men’s shelter resident Joey Jaco, who is in his second stay at the facility. “Without this place, I wouldn’t have anywhere to go.”Lighthouse Full Circle has beds for 12 people, according to founder Nathan Smith. The homeless shelter, open to only men, is located at the old dog pound by the fairgrounds.
