I was descending Monarch Pass in CO behind a cattle truck, which I could not see around. Driver was nice enough to wave me around, but I stayed put. The shoulder was crappy, so railing the truck allowed me to safely take the lane. I remembered something I had read about riding behind cattle trucks and kept my distance in case one of the bovines went No. 1.
