May 10, 1991 - Lazbuddie, Texas tornado carousel. Maybe not an obvious choice, but think about it... A big dusty slow moving tornado, with full-fledged satellite rope tornadoes constantly forming and dissipating all around it, the whole thing rotating at a stately pace, everything perfectly visible... Keep your boring old wedges, this is the kind of stuff I like to see! Well OK, I want the wedges too, but really I'm hard pressed to think of a more interesting and visually awesome scenario than this one. And I get the impression that there was quite a bit more to this event then what you see in the well-known video. My kind of storm, for sure.
June 23, 1998 - Columbus, NE tornado. I've never had a chance to see the famous "Crazy Farmer" video in its entirety, but what I have seen leaves no doubt this one is right up there in it's awesomeness factor, even if it is just a single tornado. Big drool factor, for sure.
May 3, 1999 OK - How can you not have this day on your list? But for me it's not necessarily just the Moore storm, I think the number and variety of tornadoes produced by Cell B almost beats the big F5, barely. And the only other chase day that could even come close in terms of multiple photogenic tubes is...
June 24, 2004 SD tornadofest. The incredible life-cycle of the Manchester tornado, plus many other tubes in rapid succession... Unbelievable. This and the May 3 OK outbreak were probably the two best days ever for multiple powerful chaseable tubes.
