Thanks for the chuckle, RJ. I hope you enjoyed your vacation. I rarely post, but for many years have silently read and enjoyed the comments from you, Sniktaw, rickschlosser, Andrew from Toronto, stressfree and Sandia. I always learn more from all of you than the actual article - even when you're sparring with Catou :-). Thanks to you all for sharing your perspectives. Have a great rest of the summer.
