Slightly different tack but...
It's great that cycling is popular in the USA and it certainly has a lot to do with the Lance factor. The Lance thing is as much about him and his story as it is to do with cycling.
IMO it is a mistake for the UCI (or anyone else for that matter) to get too focussed on trying to appeal to a US fan base. I'll try to briefly explain my thinking...
I am not a big fan of national generalisations but the US sports market is so dominated (saturated) by their own Pro (and colleagic) sport scene there is not much space for anything else.
Look at soccer (football to most of the World!) the biggest sport on the planet and it barely has a foot hold in the States. Beckham came big fuss, Beckham left all gone quiet again! Sure loads of folks (particularly women and children) play soccer but it has little traction the 'market place' because of the domination of other sports. Likewise even more established sports like (ice) hockey can struggle to establish a new franchise. Same is true of Formula 1 trying to get a decent following out here.
If it were up to me I'd stick to getting and keeping the sport healthy just about everywhere else before I got into promoting cycling in the States (I would start in Germany
)Sorry if this is not folks in the US want to hear but...to get things going in the market here (and it is a market more so than Europe or other parts of the globe) is v. expensive and the popular fan base is fickle.
I live in Vancouver BC (although originally from the UK) and cycling is hugely popular here much like the rest of the west coast of North America. I would love to see a race like ToC up here - maybe it could even be around the same time of year - it would be awesome. If it happens great but I wouldn't expect the UCI to go out of it's way to make it happen.
