Prescott is a 4 seasons kinda place, I enjoy all of them. For you i would come any time from spring to fall, yes there will be tourist but that's anywhere. there are lots of activities and fun things to do around here like Fishing from 1 of our 5 lakes, Lots of 4 Wheeling, mine exploring, Hot rod shows and runs, Art shows (if your in to that I'm not) Air shows, Hiking, hanging out at Whiskey Row, ect. you get the idea. If you bring your jeep let us know, a group I 4 Wheel with will take you out for the day.
Hope that helped a little.
**** it, GAS IT!
