The most dramatic change on the schedule is that Pikes Peak no longer has a Busch Series race, that event has been replaced by a July 22nd night race in Martinsville. The Busch Series previously raced at Martinsville from 1982 through the 1994 season when it was dropped from the schedule.
Here is the complete 2006 NASCAR Busch Series schedule.
