or prevent some people from going out there? >> well, chasing either for recreational purposes or scientific like mine is very difficult, almost impossible in an urban area, because basically, everything breaks down. people are trying to evacuate, police are closing off the roads, trying to keep people from getting in, and it becomes quite chaotic. >> is there anything new to this season's outbreak that you haven't seen before? because there was a tornado drought up until a couple weeks ago, now we've seen a large number of tornadoes. >> the number of tornadoes is still well below average. this is one of the calmest tornado seasons in years. however, the tornadoes that have happened have recently been hitting major populated areas and that's what's unusual. that's probably just bad luck. if these kind of tornadoes, the el reno tornado or the moore tornado from several days before had hit rural areas, we wouldn't be hearing about them. that's more typical. so far, we've just had some very bad luck. hopefully future tornadoes which
