Hi Wayne -
Thank you for making me welcome. We are just now coming to the comfortable period of the year (for the southern part of Arizona). The South Rim of GCNP will be OK for a month or so but then too cold for a while. North Rim is already COLD and the road may be closed, I am unsure. Next summer? A trip to North Rim is a commitment of time and money in any case but well worth it. If you make plans to come to Arizona let me know -
