I need some info on who can attend the GM Heritage Center Tours during the BCA Meet.I read on the website it is not open for daily tours. Can GM retirees and their families visit the center without going on the Tour through BCA? I am not presently a member of the BCA but am planning on attending the meet in July. If I'm not a member and do not have a buick car to register for the show, I own 4 antique vehicles at this time,all GM,just not a buick, YET!!!! can I still register and get to take the tour to the Heritage Center? I looked on the BCA site for info but thought maybe someone could give me clarification. Thanks!!
