Summer thunderstorms and cloudscapes are some of my favorite things in the whole universe. There was one yesterday afternoon, on the 18th. The clouds were glorious. This sketch is from my 2005 journal, where I tried to capture images day after day along with my written entries. I have kept a daily journal now for 40 years, since 1968. Not all the journals have pictures.
This looks like watercolor, but it's actually made with markers.
