Lightning Storm

Today we drove down to Indianapolis. It was a very nice outing: shopping, eating, sightseeing, more shopping, more eating, etc. Anyway, the most exciting part of the day came during the drive home. We were treated to a wonderful light show as a huge lightning storm rolled across the state directly ahead of us. Lots of pinkish-orange flashes high in the clouds, no thunder and no rain until the last 10 minutes or so. As soon as we got home, I made this (very quick, very rough) sketch, trying to capture what it looked like...
