Please don't be in a big hurry when you drive to and from Mt. Bachelor. If you need to pass, make sure it's safe to do so. Near Sunriver is a rural area. Many driveways and streets intersecting.
Both of the people ahead here passed me over double yellows and the second one at a four way intersection to boot! Then came the horses. Hope they learned a lesson the easy way. Next time could be the hard way!
