Wow. They were not kidding when they said everything was Free.. Just left there. had to come and comment about it real quick before I head back to see the next band that takes the stage. food, music, cars, and all the extra events are excellent. having a blast Over there at Tucson Dodge's Retro Event. It goes till 7:00 p.m. I do believe. If you get a chance you should go and enjoy yourself. Bring the kids there's actually balloons and train rides. they will love it.
