I'll be there. Its a good time. There should be between 30-40 samurais there from stock to extreme. The event is free, just pay for your campsite and pitch in like $5 or so for the BBQ. Its a great way to meet the guys in this area. I am in Windsor Locks near Bradley Airport and its about an hour north of me. Hope you can make it
