I have been storm chasing now for 11 years and have now seen, as of this past Sunday, 23 tornados and 1 land spout. He is my break downs for ya:
TX - 3 (2 in May 2002 near Happy TX, Patricia in 2006, Landspout in 2008 on TX 70 south of Palo Duro Canyon)
OK - 2 (Edmond and Peidmont in May 2004)
KS - 12 (11 on May 7, 2002 between Mullinville and Pratt including the first one to hit Greenburg. Greenburg would be hit again 2 more times since. The other one was southeast of Hoxie in 2007)
IL - 4 (Plainfield on Aug 28, 1990 although this i did not chase, i did see it. It was 2 miles from my house at the time and i was a freshman in HS. Greenville in 2000, Utica and Joliet in 2004)
WI - 1 (Arkdale, April 10, 2011. Closest i have ever been (and ever want to, prefer no closer than 1/2 mi) to a tornado, 1/8 mi)
Manitoba - 1 (2007 near Oakville, although our team, College of DuPage, was on the south side of the tornado about a mile away, Reed Timer got this video from the otherside of it.

I also went back to find some of my other photos. Here are some of the best that i took back in 2006. Look under Dan "BWER". My best lightning pic is in there with the Texas flag near Breckinridge TX
