Wow you're my hero and I mean that! My hubby and I rented bikes in sonoma and road to napa, taking trinity road and dry creek road. This looks a lot like that. We live in mn and I was not prepared for that type of climb. I am also petrified of heights! You have to be one awesome cyclist in amazing shape to have done this I walked my bike at least 1.5 miles of the 3 mile climb)!
