It was hell trying to meet up with people at the actual car show last year, just soo much to see and so little time... The banquet and happy hour are the place to meet people!
Check out the SevenStock.org webiste
for info on the Banquet and Happy Hour (well, happy hour info isn't up yet, but the banquet is)
Yes, there will be big wigs from Mazda at the Banquet, that you can talk to, and just chill with... it was really cool last year talking to Koby-san for over an hour about life, rotaries, Mazda and stuff in general!
