I typically go light on the grain before hauling anything of mine. Some travel well and will typically handle it, but hauling is a stress and I like to remove as many variables as possible. Like was said before, just keep em on their same routine. There are some variations for some people, but typically your endpoint show is most important. You dont want to go to any extremes to win a prospect show and then end up ruining him for his endpoint show, therefor just keep on treating him like you would if you were not going to Denver and you should be fine.
