Hi Folks, I have a week to spare in the Fall and my wife and I have decided to go to Arizona. Here are some concerns for which I hope the good folks around here would be able to offer some advice. 1. Is it a good time of year to visit (October - November)? 2. We are flying to Las Vegas and drive from there to Flagstaff 3. Flagstaff will be our "base" and hope to be making daily trips to nearby attractions such as Sedona, Grand Canyon,etc. 4. Any other attractions we should not miss? 5. What lenses should I carry? Thank you in advance, everyone.
