I stopped using C470 several years ago; I drive the "back way" on the Red Rocks side of the hogback. That's the route I used to take before they built C470. Much nicer scenery, much less traffic. The stretch of 285 between Indian Hills and Morrison really isn't that bad, the worst traffic is between Windy Point and Pine Junction.
When I lived in Brook Forest, I was about a mile or two up Forest Estates Road, which is at the end of Brook Forest Road, the turn off is right past the Brook Forest Inn. Back in those days the Inn used to be an actual Inn, with bar, restaurant and rooms upstairs that people lived in. I've seen it go through so many changes over the years I don't even know what it is any more. There was a time that my band played there back when they had a bar and dance floor.
