Yes That would be my question also. I would defiantly recommend Tombstone if you are a Western history type guy like I am. If you are in Northern AZ, take old 66 from Kingman to Seligman. If you have the time take 66 from Kingman to Oatman also. Oatman is a hoot to go see. Good trip. Also if you have never seen the Grand Canyon, go see it! The first time I was there it was "Jaw dropping" awsum!
Get an AZ map and look at some of these places. February is a good month to take old 66 from the CO river through Oatman, then to Kingman, then to Seligman and then to Williams. From Williams go to the South Rim of the Grand Canyon. You will be GLAD you did! Absolutely a gorgeous ride!
But one warning for you. If you do go to Williams and the GC, make sure you check the weather first. It could be real cold and you could get some snow. The southern part of AZ should be a no problem area to ride if the northern part is going to be cold.
