Hopefully Nintendo will make a live stream available for the final World Championships and if they do, i'll make it available to everyone to watch here.
I'd love to head up to Seattle to try my hand at qualifying but Seattle is a bit of a drive and I KNOW I won't be able to beat the best Mario Kart 7 players in Seattle. Still would be fun to check it all out though. If you are planning on hitting up a qualifier in your area, let me know.

That could be a fun day trip up to Seattle on Sept 10th...
