BELFAST, Maine — Waldo County doesn’t have any homeless shelters, and that’s something that might be getting in the way of an accurate count of people who are without stable housing, according to advocates such as Allison Harrell. That’s why she and others are gearing up to try to get a more comprehensive figure of the county’s homeless and housing insecure population during next week’s annual national Point-in-Time count. “If there is no shelter in your area, there needs to be some kind of count,” Harrell, who is part of the Waldo County Homeless Coalition, said Tuesday.
