I had just read the winter "Still.....Keeping Track" member profile provided by Jeff Greenburg. Occasionally, I search for photographs of the 1974 Mid-Ohio Trans AMA race which Jeff and I both competed in. The last web scan provided this photo from 1976 and an interesting web site to review further.

"From former 125 National regular Jeff Greenburg: "Here is one of Werner Straub's pics you could maybe use for your 1976 piece. I'm sure Werner would love it.... That's me sliding out the front end!"
