Here's a photo a friend sent to me of Mac Yates after he won a National at M.A.R. in the 70's sometime...

Thought you's like it.... I raced with Mac in my 280Z..... we had some great races ....except everytime I'd go to pass him .... he'd cut the apex to much and through rocks up and brake my windshield..... then I'd really pass him and do the same .... but he had no windshield.... we always had a good time at StLouis...
