Informative article on how new-fangled shafts came about.
Thanks for that. I went to school with Don at OU in the early to mid 60's. He graduated and I didn't. I started my own little food business there my Sophomore year and was soon making more money than the professors. That was the end of college for me.The 'Owen' mentioned in that article is Don Owen not Bob. He is the 'O' in OB shafts.
