Jim,
31, yes, but 9-hole tournaments here are routinely won with something like 27. One misstep and you're out. Ouch! Whereas the drama (as we did NOT learn from Rory this weekend) is how you come back from the random poor shot or bad hole. (Ouch! again.)
Interestingly, if you look back to the Bethpage Virtual US Open 2 years ago, it was won in the final round by a 66, and I think there were 200 qualifiers. (I got this from the archives as I joined after that.)
