Thanks! I replace the earlier version that had the three photos together and it wiped out previous comments. Thanks 'steampowered' for your suggestion to go with one that did not obscure the towers too much. I chose this one because of the mood I felt the clouds create as they moved around the Sears tower.
@taffy I think that any of them would have been stunning but this one I like - a lot. I'm afraid that Cowfold, West Sussex doesn't have anything to compare to this.
