One thing that I love about T/D is that you see altereds and front engine & rear engine cars. Nice mix. That is a great class. I know that I'm, uh, mature (heh), but when I see T/D running on a 6.10 index, I can't help but remember when T/F was getting ready to break into the 5's, 1972. If I saw a 6.10 then, it would have been crazy quick.
