I admit I'm bummed about this move personally, since PIR is practically in my back yard and racing there allows me to participate without creating a huge carbon footprint.
However, I understand that race organizers don't generally worry about the effect this has on entry-level racers like me -- their raison d'etre is to cultivate the higher echelons of the sport so that Americans can compete at the same elevated level as their European counterparts. There has also been a general professionalizing of cyclocross, which will cost the sport at least a little of its grass-roots origins and vibe. It happens. (No sour grapes on that score, just making an observation.)
It's possible that organizers are trying on purpose to shrink participation numbers -- especially among amateurs -- because of the complaints by some that the number of racers has grown too large for some US venues to handle. Moving the USGP to Bend will certainly accomplish that secondary purpose.
On the downside, Bend is simply too far away for a lot of racers from the I-5 Corridor, and adds greater time and expense; more days off from work will be needed for travel time, and then there's the added expense of hotel rooms (which cost considerably more in a resort town during ski season than they do in otherwise-ordinary, rainy Portland).
So for the higher categories of racers, this probably won't be a huge deal. But for folks like me, it will simply end my cyclocross season earlier. That's either a disappointment, or a chance to gain a fresh perspective and a few more weeks of rest and recovery time. Depends on how you look at it.
