I can't understand why people find this a bad idea.
1. Not just any international location: This isn't about just going somewhere else for it's own sake. The TOC moved to May. Most Americans don't know the Giro; they all think the TdF is the only race all year. Cycling is moving more global. ASO owns half the Vuelta, is partners with TOC, and runs the biggest race on Earth. So RCS can either stay in Europe, watch PT teams split between a growing TOC and Giro, and risk becoming a regional race or sell out to ASO; or they can keep up and build brand/race awareness in the biggest market in the world. The US isn't Bukina Faso (although with the fiscal crisis it may start to resemble it soon). They aren't competing against Missouri (off schedule). They are competing for talent and stature against TOC and ASO in the US and over their TV deal on a direct scheduling basis.
2. Logistics. The map says it all:
http://maps.google.com/maps?client=firefox-a&rls=org.mozilla:en-US:official&hl=en&tab=wl
It's 1,200 km from Middelburg, NL to Savigliano, IT. Rail, road, it's a day transfer and they include a rest day to account. Other than the time difference, some of which scheduling can solve, morning stage, etc. the logistics just aren't that much more crazy. Millions of people in far less physical condition, travel further, overnight, without rest days, and go into major meetings, with high stakes, where their professional skills are tested significantly, and perform exceptionally. Reading some of the comments here, you'd think RCS was planning to move a nursing home overnight to Italy.
3. Money. Why wouldn't RCS want to try and increase exposure, broaden sponsorship, and increase rider participation/choice? The riders are just meat popsicles? Come on. Increased name recognition on a world stage and more potential sponsorship are worth something to the riders too. You think they'll do a soft sprint on Pennsylvania Ave, complaining, "oh I'm just 'ze meat popsicle, merde?" There is no real money in this sport to begin with, that's the problem. As fans, I'd think people would be excited to expand the sport beyond lost Italian roads nobody's ever heard of, save the Romans that built them 2K years ago.
Benvenuto Giro. Buona mossa e ben fatto!
