Just as a suggestion ... I like the idea of getting together, but because of a prohibitive work schedule I most likely wouldn't be able to attend. But as a possibility for future years ...
My wife works at GM Tonawanda Powertrain as an engineer. Every year around the end of July they hold a car show on the plant's front door. Seeing as how every HHR engine originates from this plant, maybe the WNY/Northern Pennsylvania crowd could crash this show one of these years? I mean, I know it would probably mean a lot to the guys working there to see a fleet of their products returning to the spawning grounds. This idea was tried about a month back when a Corvair club toured the plant (the Corvair engines were built there, and the club guys viewed the plant as being just short of Mecca.).
Probably wouldn't be able to do it this year, as the show is tomorrow ... but maybe in the future?
