2 weeks of rain and half the forum wants to scrap the TT. Quite insane, isn't it? And this has nothing to do with the TT and less with sports. Every Outdoor activity could be rained out. Thats no reason not trying to do it, in worst case, there is another year next year.
Was there ever somebody who asked for scrapping wimbledon, because it could be rained out? bullcrap that is! I can't when the downhill world cup on the world famous Streiff was last run over the full distance. Every year they have problems with snow, fog, rain or even the sun. Nobody stops coming, nobody asks to scrap the race.
And would it be so bad, when some spectators would stay at home? In the last years I only read about full ferries, full hotels, full camping areas, ... Perhaps prices would drop for everybody, when the run to the island would be a little smaller.

But what I would want to know is why it is not possible to race in the wet. Is it the modern bikes and tyres or what. They race in the wet on circuits. They did it on the mountain course for nearly 100 years. And I can't see more heavy crashes back in the day.
