Painting outdoors is a delightful process and is better known as Pleine Aire to the french, who started it in the mid 19th century.
When people stop to look over my shoulder, I often invite them to to give it a try.

One watcher confessed he planned to build condos for skiers on the mountain I was painting. “Do you really have to scar such a beautiful mountain?” I asked.
Why not paint it instead? Soak up all that restless energy. Make your mark, but leave no mark.

Truly, this way of painting is a great way of possessing a landscape without actually owning it.
