Yes, I did a lot of business in Europe (and Asia) in the '80s. Since I have been chasing the Lost Tribes of Israel for over 20 years I took advantage of the travel to schedule extra time for "personal tourism". Visiting the major Celtic sites at Hallstadt Austria and Neuchatel Switzerland were highlights. There is another large Celtic site south of Stuttgart Germany I would like to visit someday. (Sounds like the beginnings of a fun trip, doesn't it?)
Sounds great, send me a postcard.
