Here's an excellent sight to salivate over awesome roads in Oregon.
The main site is http://linesthemovie.com
A index of the movies filmed on the bikes is http://linesthemovie.com/flash/index.html
I missed going on the Mary Hill Loop last year on the Gorge at SBNW. The event is on in the last weekend of August. Highly recommended. You can do areas and roads such as Mosier Loop, Rowena Plateu, Mnt Hood, Larch Mnt, Windy Ridge etc.
This year I will go down again but do my own ride. I'd like to take in Fossil OR, and where the hell is Bake Oven Road. Just Jacked over Oregon.
