Thanks for posting that video.  It brings back many memories.  I rode the Jack Pine enduro on four occasions.  1971,72,73,76.  The first year 1971 I rode a borrowed Triumph 500, only made it 60 some miles because I crashed heavily to the end of a hard packed sand road when the throttle stuck open because sand bound up the carburetor slide.  In 72 I tried again on my new Honda xl250.  crashed again into a ditch that snuck up on me.  I had a flat shield on my helmet that was filthy from sand and glaring sunlight and didn't see the danger arrows.  73,was much better, rode the same xl250 and finished the entire 400 miles and finished 23rd in the 250B class.  76, I rode a new 76 Yamaha xt500, and only finished the first day.  Fun times.

Motocross in the’60s and early ‘70s still had a few Brit twin riders around here. Maybe Bob was one of them?

Actually, the Triumph 500 was a very popular bike for enduros.  They were so versatile.  A fellow named Bill Baird was a seven time national enduro champion during those years riding a Triumph 500,  Gary Nixon won the Daytona 200 and was a two time National Champion with a Triumph 500 based road racer and flat tracker. Rule changes and the popularity of lighter weight two stroke bikes signaled the end of the glory days for the Triumph 500.

Those were the run what you brung days.  My boss at the time was a retired Marine.  After WW2 he was working for a Harley dealer.  He told me when it was time to get ready for the Jack Pine.  He would get off work after lunch on the Friday before the run.  Ride up to Michigan from Rochester, NY during the night and be on the starting line for the Saturday morning start.  Ride the run on Saturday and Sunday, then ride the Harley through the night so he would be on time for work on Monday.
