Go East! Go East!
Nice rides north of Chico - esp. thru Susanville.
Lava Beds has a great loop with no traffic.
New bike trail from Klamath Falls to the Sycan Marshes.
Willamette Valley has some pleasant rides.
I vote for the U.P. Far less traffic then the TransCanada.
Plus it's inhabited by Yoopers - a rare and exotic people.
Apostle Islands are super. Porcupine Mountain #1.
If you have time - do the Keweenaw Peninsula.
Grand Island off the coast at Munising is a cyclist's paradise.
Then you have Pictured Rocks.
Ya! It's the Yoop for me.
