Well I don't have any kids, but a do have a couple of Cummins I like to blow black smoke with but I usually only blow coal dust on people that piss me off, which when I go to the city is about every other one. I really like dusting those Subaru's with green peace stickers on them driving slow in the fast lane.
Seriously there has to be some Mopar heads in the Provo area and they best thing about Mopar people is that they usually don't mind helping out other Mopar people, especially young ones.
