Mitsubishi? In-N-Out Burger, I-10 & Ray in Chandler, 2nd Thursday of every month starting around 7PM. AWD? AZAWD Marina Meet, some park by Tempe Town Lake on Saturday nights. Anything goes? Scottsdale Pavilions, 101 and Indian Bend in Scottsdale, every Saturday evening, year-round, weather permitting.
Pick your poison. I'm sticking to INO 2nd Thursdays, personally. Tucson was in the house last month and we might have some Mitsu 4WDs showing this month.
