Jan, sorry for the delay. Believe me, if I can make it I will. I have a 5 year old son who lives with me and his Mother lives in another state, so I am responsible for him. I could ask my Parents to keep him while I take a short vacation for the Meeting in Kassel. Or I could bring the Family for a 2-3 week vacation away from the scorching summer heat here in austin texas. I don't know yet but I'll keep in touch. mfG, Stevie
