There are three planned stops on the cruise:
1) Fuel stop in Wickenburg, AZ - about 60 miles from the starting point
2) Fuel stop in Kingman, AZ - about 150 miles from 1st gas stop
3) Lunch at Martin Swanty Dodge in Kingman, AZ. The group coming from LA (if on time) meets up with the Phoenix group here.
The group kind of stays together, I thought people stayed together better last year. Some people go faster than others (people with a 3:91 gear typically don't drive 85 mph on the highway), but lunch in Kingman is at a set time, so if you go ahead you just wait at the dealer for everyone else to get there. The newer cars also don't need to stop for fuel every time, but I do anyway because it is so cool to see all the cars at the gas station.
