On a trip to Atlanta , I had a carry-on bag filled with my painting supplies. I got the airport the requested 2 hours early and got to the gate to find out that we were delayed another 2 hours.
I looked at my bag and thought “Why not?”
Finding a seat near a pillar so no one would walk too close, I set up my tripod and pochade box (paint box).

I spoke a bit with the people seated next to me. And one of the gate agents came over to see what I was painting. But other than that, I was in an extremely crowded airport and no one paid any attention to me. At least none that I’m aware of.
I began painting the gateway door and window with the plane beyond. In front of the window was a woman sitting very still reading a book. Perfect! A model who didn’t move!
When I was almost done, the woman in the painting got up to leave. The lady sitting next to me caught her attention and said to look at what I’d done.
The woman was thrilled that I’d painted her and ended up taking a photo of both of us with the painting. It turned out she was an artist herself, a nature photographer. Beautiful work on her business card.
