Montana did raise 2 pro wrestlers the most famous though was not born in Montana but he did grow up, went to high school and was billed from Billings Montana.
The man I am talking about is Gary Albright. Albright married into the famous Anoai and had a great career in Japan. Albright also wrestled for UWF and debuted in Stampede Wrestling.
Albright was mostly a tag team wrestler and won a few tag titles especially with All Japan with Stan Hansen and Steve Williams.
Albright was considered a great guy by his fellow wrestlers. Albright would die in the ring while taking a bulldog in 2000.
Because of his titles that he won and being related to the Anoai family Gary Albright is the greatest wrestler from Montana.
