I have waited my whole life to chase out in the plains since I was a little kid. I finally got the chance to do so in 2008. There wasn't a cloud in sight for the first 4 days. Mark toured us around recently devastated Picher, OK & Greensburg, KS. When the storms finally fired up, Mark explained to us, in detail, not only where to find tornadoes, but also the evolutionary stages of a storm. Mark also taught us how to forecast. We went from no clouds, to a storm producing funnel clouds, to an EF1 tornado, and finally, to a 7 minute long video of an EF4 tornado. Since then, I have become a lifer with Mark & WeatherGods, Inc.
