A nice evening at Kenny Park today. Blue sky, glowing light, snow, but with temperatures in the low 40's. When I was in Maine, I was fascinated by the lichens growing on tree bark. The lichens obscure the bark patterns that we are often familiar with here in Ohio. Red oak, for example, did not look like red oak because the long, flattened and shiny strips of bark were obscured by the lichens. We don't have lichens covering our trees here in Columbus.
