I don't know why nobody has mentioned the TDR's (Turbo Diesel Register) event called "May Madness." It lasts about a week, usually the first week in May, I believe. I've never been but from what I've heard it is the most comprehensive diesel event in the U.S. There are seminars, partys, pulls, races, partys, seminars, partys, and did I say partys? Seriously though, I've never been YET (planning to go to the 2008 event) but I've heard that it is the best all-around diesel fanatic get-together in the country. It is held in Pahrump, Nevada so you could visit Las Vegas, Grand Canyon, Hoover Dam, Casinos galore, etc. The TDR is a Dodge Diesel group but the event is open to all makes. From your picture, I see that you have a Dodge, though, so you'll feel right at home!
And guys, what is the TS event that you mention? I know what Scheids Extravaganza is. I've been to the Indy Nationals. I want to go to the Texas Diesel Nationals in Baytown next year, but what is TS?
