GCRocketman I rode my mountain bike in the pack forest a ton the summer of 2010 and never saw one grouse. The only thing that I did see was an owl. No deer, no elk, no bear, however, I did see a lot of people except for when I was riding in the southeast side of the forest. Not to say that they aren't there, but it might be that there are to many people around. Good luck and try the roads less traveled.
