by your user name it looks like you are in Arizona. I went to Phoenix Union back in the Early 60's. My wife and I had plans to fly to Phoenix next month for combined 36th anniversary and my 65th birthday, driving to Flagstaff and spending 4 days on the Rim with travel on the Grand Canyon Railroad. However, with my recent surgery we have cancelled (maybe later) and guess we were lucky in doing so with the fires there. Canyon is probably real smoky.
