Here's
a previously unsuspected (by me) revelation. The inside back cover of a program
for January 19, 1958 USAC Midget Road Races! It looks as if they used the
whole and entire Grand Prix circuit. I have no results, pictures*,
or lap times.
More details with program cover and entry list at Old
Paper 6.
Two other notable items: - Look
at the Turn Numbers. I wonder if USAC was using something current with RIR, or
if they just called it the way they saw it: Turn Four is 3, Six is 5, Seven is
6, Eight is 7, and Nine is 8.
- See
the "Club Circuit" annex that takes off from Turn 7 (Eight in my lexicon).
I remember some roads leaving in that area, but never followed one and don't recall
any reentry attachment to the pavement there. I don't know if it was ever actually
built or used. If I read the legend correctly, addition of the Club loop would
make a total lap 5 miles long.
