I have adopted a total of four Mustangs from the BLM. The first time, I got a four year old mare and her two month old filly. I paid $500.00 for the pair, that was about 15 years ago. The mare was taken to a trainer and broke to ride, we kept her for about three years. The baby is now a beautiful stallion. He is halter broke but we never rode him. Then about three years ago we went to another adoption to look around and ended up coming home with a weanling colt for $125.00 and a gorgeous bay mare for $25.00. Your enclosure has to meet certain requirements and the horse isn't officially yours until you've had it for a year and then have a vet come out and verify it is healthy. But yes, a wild Mustang can truly be tamed.
