Your best bet is probably the World Cube Association. It appears that there's a championship competition in July in Las Vegas, NV. http://www.worldcubeassociation.org/results/c.php?i=WC2013And here's another site that features quite a few competitions all over the US. http://www.youcandothecube.com/compete-now/
