It all boils down to whether Valencia has its ducks in a row early on. There are so many people who won't go back to sandia for whatever reason and will probably pop out to the new track to give it a go. If they find the track is well constructed and well run, then they'll stay and word will spread and others will try, leaving sandia in the dust. Of course, no matter how good the track, there will always be whiners, er winners.
