Been over to the IoM and watched it for many years. It was one of the annual pilgrimages for myself and a few biker friends up until just a few years ago. It should never be banned as those taking part (including the spectators) all know the risks. It is one of the few totally unadulterated courageous sports left and those taking part have massive cahonies and equally impressive skill. If people don't like it, don't watch it and don't go, but let those who find it an extraordinary experience, one of the most exciting spectator sports you'll ever witness, well alone. Having ridden the circuit many times, I can only imagine the sheer joy and terror combined that the TT competitors must experience!
