So I've got some additional details on tomorrow's 2006 Pine Nut Cracker for those of you making the trek into Northern Nevada. According to the race sponsors, this year's course will be the same as last year's. I found these maps of last year's course, courtesy of the Reno Wheelmen website:
They also had an elevation profile (click picture to enlarge):
There is also a 3D map of the course, if you are interested.
The sponsors also said that they were adding a team support/feed site where the return trail touches the road (see map). In addition, they confirmed the this event is a qualifier for US MTB Nationals. You can get the full race details on the 2006 Pine Nut Cracker here.
