The drive down was long and a bit stressful - driving a 10 ft trailor packed to the gills with frozen bison meat that you are trying to keep frozen (in 100 degree weather) isn't on my list of favorite things to do. The days were long and we always had that fear in the back of our minds that the bison would thaw. Praise God, the stuff stayed rock solid!! All this is new territory for us and we learned a lot about what we will and won't do next time.
Won't - stop outside of Vegas for any reason (major culture shock and way too many people)
Will - buy a reefer unit for trailor so that we won't have to worry OR buy dry ice.
