By 1977 I was beginning to learn Bob Hannah was not like most of the other riders of his era.  Here he is during a riders meeting.  I don't know the whole story behind "Leaky Larry" on the folding directors chair but he was doing his own thing emptying out his boots during the meeting.  Yamaha Team Manager Ken Clark seemed to be suspicious of why I was taking pictures of this scene.

Later in '77 I took this shot of Hannah's speed bag hanging off a door on the Yamaha Support Van.  I never saw him use it but it had to be something of note by other riders seeing this "bull bag" in the pits.  By this year Hannah seemed to be winning most of the time. 

I have mentioned it before but there really were many more bike brands during the '70's.  Here Billy Grossi is riding a very rare Mexican Carabela in '78.

If you have ever been in the pits during a Supercross you can appreciate the difference of how it use to be.  There were no signing tables or lines.  You simply walked up to your hero like Jimmy Ellis and asked him to please sign something for you out of the back of the team van.

Another rare bike was the Harley Davidson motocross bike of Marty Tripes in '77.  These were Italian made bikes with Harley badges.  The Harley MX team only lasted for a couple of years.
