Here's a dandy. Don't see many metal valleys around here but I love them. This picture is super washed out, I'm planning to stop by on a cloudy day to get a better picture.

David, well done! Mike, you are amazing! Credit to the both of you!
What's an internal gutter? :laugh:
There are hardly any internal gutters here, mostly on old farm houses. Many of them have been blocked in and just have a smaller sloped kickout on the roof with a fascia board added to allow for a K-style gutter.
