While the Pinto has a few broader groups (such as this site) I'm not sure there are any state club chapters. At least in the 10+ years I've been here I don't recall any. Where as some cars have clubs that I'll equate to a professional ball team, Pinto owners seem like the type that will get a game going if enough people happen by an empty lot.
That said I may be wrong, but after 5 days of not getting an answer I'm incline to think I'm not. One thing I like about this site is Pinto owners seems to be the salt of the earth. There seems to be little of the "I'm THE expert..., who do you think you are," kind of posturing that occurs at other sites. Here we lowly Pinto owners are more like two homeless people sharing their food (and I mean that as the highest compliment of vehicular humanity).
