Though my plans were severely downgraded, I did get out on the trail on my Trek Pilot road bike. This is probably a weird combo, but I went with a Vittoria Randonneur 700x28 (from my LBS) on my rear wheel to safeguard against all punctures. Wasn't sure a 700x32 would have fit. On the front, I had a Pasela 700x32 (from Nashbar). Less puncture resistance, but more surface area. The combo seemed to work nicely. Going to go for the whole Katy in the fall, I guess. Bummed I didn't get to do more this time. Fun challenge.
