Yesterday I took a ride out east and stopped at a "cut your own" Christmas tree farm.
I had no intention of getting a tree. I just wanted to sketch. I parked my car along the opposite side of the street. These cars were parked in a line side by side amid LOTS of other cars...maybe about 60 of them...almost as far as the eye could see. I focused on just one car at a time and took artistic license to leave out the others. I watched for when they carried over a tree by a car...that would be my model. I figured I had enough time to sketch the activity while they tied the tree to the roof...and I was right.
