We've all seen countless videos of tornadoes over the years, and there's no doubt that as the technology gets better we'll continue to see high-def footage shot very near a tornado.  In another 12 months I may look back at this video and say it was nothing, but right here today it's the most insane footage from terrified storm chasers trying to outrun a tornado.  Yes, hard core storm chasers screaming, "If you don't drive south we are going to die!!", will get your blood pumping this morning.
