In case you haven't seen it on the MS site, looks like they will have both the Lunch Express route AND the Bechtel Challenge Park Routes going for day 2.

I am going to do the ride and am planning on driving in tonight with a friend on the Exxon team who has a hotel room in the La Grange area and will meet with the Exxon team for the start Sunday morning.
Safe travels and riding to y'all who are still doing the ride.
