I agree. We had it over here in sa a few years back. i think its important to spread the major events around the country. The obvious reason is that it helps grow the sport. It is very difficult for the sport to grow to the level we all want it to grow to if it is kept in the same areas. The tdu has grown the amount of following for cycling in SA. This encourages more pople to ride, sponsorship dollars come into the sport(our crit series is growing well), and i think car drivers attitude to cyclists is improving.
Also its not exactly fair to have some people have to travel across the country every year, when other people have it in their home town.
It seems logical to share.
