Joe, they did the same thing at Vegas1, although the second Friday session starts even earlier, at 4:30. One possible reason I had heard was they're trying to avoid having the one "hero session" but this doesn't add up because there are other events that have a late 2nd session, starting at 7pm, as well as the fact that NHRA adopted the new qualifying format. Who knows? Obviously not me, I just know I'll be there! See you there Joe.
