Thunder is a 6 year old Mustang. He is broke, but hasnt been ridden in several years. He should be considered green broke until otherwise tested. Would make a good project horse for an intermediate/advanced rider. Good portfolio builder for trainers. Easy going and quick learner. Has never bucked. Doesn't like feet being picked up at first, but will come around with a little work. Selling to get something more suitable for kids. May trade for kids horse. Pictures available via email.
