I have considered a chair. I'm sure it would sure be a pleasure to sit in after a long day. However the weight has always seemed prohibitive. Maybe if I were younger and going to a base camp where I was staying for a few days I would consider a chair. I use a light weight tripod chair that folds and packs nicely into a backpack. for plein air painting, but that is usually a short walk (one or two miles is all).

In every walk with nature one receives far more than he seeks.
