Putting my 2pence worth in.
There is plenty of peaple in government that make a career out of the TT and some big government salaries rely on it. They will not let the jobs go without a struggle.
In my opinion it will be the day they carnt get the appropriate number of Marshalls that the insurance and H&SE require. I'm as guilty as anyone in that I come over every year but have  never give a thought to being a Marshall. In these times peaple are not as willing to give up there free time especially when you see the scrafices peaple make to spend 2 weeks of there yearly holidays marshaling at the TT often for some gobsh#ite to give them a mouth full. So hats of to the lads and girls thst do make the effort.
