Bill Cleghorn contributed these photos of the LeMans start of the July 4th, 1970 race discussed at length here.
 

Does anyone see a familiar face or bike here?  Bill Cleghorn identifies the man in the white hat by the crooked telephone pole at Al Coppel II, noted SCCA racer of the 1950s.

They're off and running!  All except for the poor guy in the middle of the picture who's pushing to build up speed for a bump start.   The Honda rider on the right seems ready for a helpful push from a buddy.  Grounds for disqualification?
