I did this today, had a great ride today on the 100k despite the wind.
There were some rough roads and pot holes, but they were well marked.. and IMO I thnk this rally is top notch... especially to be this close to Dallas finding a relativley safe route can't be easy.... All the intersections were well manned with police, great support, the one rest stop I stopped had all the essentials and free food in the end... I think one of the best run rallys in the area.
