In addition to listsofjohn, Andy Martin maintains a listing of 1000+ summit baggers - category 5. (don't worry its a non harmful attachment):
Not sure if there are Idahoans on there - perhaps many Idaho peaks are too difficult/remote for numbers, quality over quantity.
Mike Garratt is also worth a mention, he's about maybe 70+ away from climbing all summits over 10K in Colorado.
With a measley total of 3 summits in Idaho, I've been checking out this site and Mr Lopez book this winter in hopes of getting up some more this summer. Tim W
