So to the cloud photo that illustrates this posting. It's a lovely big Cumulonimbus taken by Dutch National Gliding Team Member Frank Hiemstra in the Slovak Republic, during the training days for the 2010 World Gliding Championships. I saw it while I was browsing his Flikr stream here and Frank kindly gave me permission to use it here.
He's clearly a cloud fan because most of his photo streams contain one or two dramatic cloud photos but he didn't let them distract him from tasks in the Club Class of the WGC, taking third place on Day 7. So thanks Frank and good luck in future, and I encourage everyone to check out the Cloud Appreciation Society.
