Has anybody stayed at the Grand Canyon, South Rim, during the first two weeks in October? If so, how cold was it? We don't have a good sense of what the weather is like, mid-fall, in this part of AZ. I don't need 80 degree days, but I also don't need snow flying around the 5th wheel. We learned a lesson 3 years ago, with 6 inches of snow on each of 3 days in Flagstaff over Memorial Day. We are trying to decide whether to do a late camping outing at the Grand Canyon or Organ Pipe National Monument, which is way south on the border with Mexico.
