Properly managed there would be no problem as a few people I know have obtained excellent riding horses from the mustang roundup program.  I would love having one or two myself if I could get my wife to move out in the country a few miles.  But alas she is a city girl.  Maybe some of the protesters forgot all it takes is an amendment to the legislation to insert the no kill clause.  May I remind some of the gentle hearted people that Cougar feed on wild horses.   Nothing in nature usually dies of old age.  Also keep in mind that properly managed culling of the herds would be effective in maintaining a balance. An intelligent approach solves more problems than immediate knee jerk reaction.  I doubt if President Trump desires to eliminate the mustangs. Never believe all you read in the press.  False news has run amok lately.
