My wife and I are staying in Flagstaff Aug 1-2 for a couple of days off between business trips and we've never been to the area. What are the must-do's while we're there? We're going to do the GC for a day, and maybe go to Sedona for some star gazing since it'll be a new moon. What else should we not miss? Budget is a little tight so no helicopter or jeep tours - need to keep it as cheap as possible since we'll be burning gas. Petrified forest? Meteor crater? Thanks in advance for the advice.
