By the time you drive from the hotel in Scottsdale to Yarnell it might be close to 2 hours. I just know that it is not as far as Prescott and Prescott is 2 hours (with ME driving the usual 10 mph over the limit). Just thought I would throw this out there for the early arrivals.
I'm arriving on Tuesday evening. Thursday would be a good day for me for this trip. I will have a vehicle. It would be nice to have company/navigator(s) for the trip. Thursday evening is also the baseball game.
