From the RUSA rules:
"If a rider arrives at a checkpoint after it has closed and the ride organizer is satisfied that the rider's lateness is due to the occurrence of something unforeseen and beyond the control of the rider (such as a road closure or stopping to help at a traffic accident), then the ride organizer may waive the fact that the rider arrived at the control late and allow the rider to continue. Poor bicycle or equipment maintenance, fatigue, lack of fitness, hunger, etc. are not unforeseen and beyond the control of the rider and therefore will not serve as a valid reason for being late."

If I remember right, at the previous PBP, they extended some of the intermediate control times due to weather. They may have done that at the Texas Rando Stampede, I know they had checked into it, but not sure if they actually needed to. The issue there was wind. If you get to a control late, and you're just moving so slow you're going to be late on every other control thereafter, that's a good reason to DNF. But if you can reasonably get back in the game, that's a different situation.
