Hi Cat: You have a great trip & a safe trip. Good luck on the research also. We will miss you on the web, but we are sure you will have gathered a lot of information, & we do appreciate your your help & having you as our friend. We will be glad to hear from you when you get back. And by the way I was afraid you might see snow, "even in your back yard", the way a couple of these cold fronts have moved south. <grin> Have a great time, & take some time out for your self also. <enjoy> Good Luck Gayle M.
