PS: Brandon, you might also want to look at tartans associated with your side of the Atlantic. There are US national tartans (all unofficial) and not a few state tartans.
Illinois, unfortunately, does not have a state tartan, but its St Andrews Society does.
But there are other US and North American possibilities, too.
And since you mention motorcycles, there are several bike tartans, too, including Harley Davidson.
Regards,
Mike
