There is a Thunderbird meet on the 24th of June in Canterbury, NH. The club is called the "Vintage Thuderbird Club" and the event is called the "Thunderama 2007". http://clubs.hemmings.com/clubsites/nevt/2007-Thunderama.html
As for Oxford Plains, we need more Y's even if they do not race they can show and win some great prizes. If they see other Y blockers race maybe they will join in in future years.
But we can have a Y meet/races there any other or every Friday or Saturday that they have a race what you bring night and it won't be so crowded.
I'm a certified nite person. Usually go to bed about 2AM. Chuck
