      <PrimaryExemptPurposeTxt>We are committed to promoting and facilitating successful adoptions of Bureau of Land Management wild mustangs and burros through a training program for regional youth and adult.</PrimaryExemptPurposeTxt>
      <ProgramSrvcAccomplishmentGrp>
        <DescriptionProgramSrvcAccomTxt>We bring wild horses out of holding by the Bureau of Land Management and place them into homes with select trainers. Those trainers are both youth and adult. They are gentle with them and train them for 120 days then bring them to one central location (our venue) to showcase them and put them up for adoption into permanent homes through a public auction process. We finish in August and begin preparing for a new year immediately. We select our horses for our program in December with horse pick up traditionally in March or April.</DescriptionProgramSrvcAccomTxt>
