This short cut may be small, but it opens up a full back route through the quiet neighborhood streets that allows us to avoid the extremely busy main road. A great addition! Just be sure to follow the clear markings - the neighbor to the East does not like people entering his driveway...

Once you've finished grinding up and out of Black Diamond you get a quiet smooth, fast and peaceful segment like this. No trespassing signs right and left. A lot of power lining going on there. Trace them on Google earth, and they come all the way from Grand Coulee.

You'll be really glad you took this minimal detour. Very smooth and easy. The huge watershed area is to the east, it's like 'Area 51' in there, you can't go. To the left you get a great view of Sugarloaf Mountain, it's one of those pyramid peaks that makes you want to hike to the top!
