Cold Weather Shelter Solution (partial)

If they can pack 200 Mexicans in a semi trailer, surely the county could invest in a small fleet of used ones, to be brought to parking lots scattered around the county when the temps drop, and include wind chill and dampness in making that determination. The more people in such a trailer, the warmer it gets, I'd say 24 max.. Porta-potty just outside, and an airlock system for entrance.Trucks segregated by sex, and also intact family trailers.
