Loma and Mack are agricultural communities and because there is no infrastructure, they will likely remain agricultural. Until there is available sewer there will not be any developments. There are ranches, hobby farms, homes on large and small acreage and homes on small, city-size lots. There is a manufactured home park in that provides an affordable housing option. Elementary school children are bused to Loma. All middle and high school children attend schools in Fruita. Wide open spaces, miles and miles of spectacular sunsets and views !
