Went to a local park and set up with an easel. I used charcoal. My first problem was the wind. I had to clamps holding the paper on top and nothing to hold the bottom so the paper kept blowing up. I'll start keeping a role of tape in my sketch bag.
So I had to work with one hand holding down the paper. I was unable to step back and see my work in progress, something I like to do. Second problem was the sleeve of my coat kept dragging on the paper blurring and making marks all over. Oh, the difficulties of being an artist.
