This time I painted from a small wooden bridge that spans the brook. Sections of the bridge planks are pitched at different angles and not level at all. Also early in the morning the planks are wet and slippery. This morning I noticed something new, large scratch marks, from a creature crossing the bridge with difficulty requiring the use of claws to maintain balance. The claw marks were as wide as my hand, so I suspect that a bear uses the same bridge, fortunately, at a different time of day.
