Well done children!Not sure about Steve Cramer but I think it would have been a Suzuki RM370(maybe a "works bike"RA)
Inside info about the Blair Shepherd SX era,my brother and I supplied the Starting Gates at all of his events,and it was amazing to"see" how he operated.It was a family affair,his son Scott was a pretty handy rider,his wife was a big part of the show,and his soninlaw was the track builder,all worked hard at putting on a good show.
I remember at the first Sydney Event,going up to his suite at the Boulevad Hotel(part of our deal was free accommodation)who were one of the sponsors,and joining them for breakfast consisting of a cup of tea and toast.We could not afford room service,and even though the Sydney Showgrounds was packed on Saturday night,Blair reckoned it was too dear as well!
The other memorable event was at Archerfield Speedway.We turned up in the middle of a tropical downpour,and set the gates up,the rain never stopped,the races went on,while we huddled under an umbrella.The next morning the sun was shining,and we sold the set of gates to the Minibike Club that had their track there,it saved us having to pack the gate up.
