Hi Mark ,
I'm pleased to hear you are being a Devils Advocate, there needs to be more people who aren't afraid to ask a difficult question,that may be unsettling for some. don't be like some riders who bitch and grizzle,most often with a beer in their hand after the racings over, casting aspersions about some one or their bike,but don't have the courage to do something about it .
Its all about a "level playing field " commonly known as the Rule Book, some people can't read it,some people don't read it,some people won't read it .
Eligibilty isn't a popularity contest,(I'd never get to ride)The GCR's aren't perfect, but they are the rules,its interesting to note that some protests in the past, have been the catalyst for rule changes !remember;
Those who protest are often called pests
Those who have their protests dismissed are called gooses
Those who have protests upheld against them, are always wrong.
