I was navigator/comms in a SAG van for the ride.
We came through La Grange Friday afternoon, and believe me, MS made the right choice in cancelling Saturday. We ferried team TacoDeli from Houston to where they were staying outside of Schulenberg on Saturday, and the rivers/creeks were very, very high (we had to divert at one point as a river was washing across the road). Considering that is the first cancellation of a full day in 25 years of the ride, they do not cancel lightly.
