Cycling is growing not declining. We want more cycling not less.
As i said before the best way to bring in a outside europe race into the big league would be to hold it right at the end of the season. That means OCtober - November, giving the Tour riders a chance at a second gt, not cutting down the existing ones, and globalising the sport (in both directions).
Sorry Cali your climate doesnt cut it. Nor does your history.
One country that does however is Colombia (+ venezuela bolivia and equador if need be). It has more history, a better climate and better riders.
Any 4th gt can only ever be held there, as a way of expanding this thing of ours, and not in Cali at the way of pimping it out for money and in the proccess destroying it - which is were prostitution usually leads. Short term gain, long term destruction.
