Yes, I have been to Kassel and also remember Emmen (sp?). The girl I was dating at that time (who I also turned into a C-body nut... She restored a '66 Monaco after we split under good terms) was American with many relatives still in Germany. I recall that we crossed the oldest stone bridge in Europe (Hann Muenden's claim-to-fame) and came to a Ford dealer.
It was Sunday, so we didn't expect to see anyone and I started looking at all the Euro-Fords on the lot. The owner of the small dealer was there and began a conversation. He was a car nut, but his English wasn't any better than my German, so poor Christine had to translate everything twice. She eventually ran out of voice, but we had a great time. I liked Germany enough to stay on two conditions:
1) I would have to have old Mopars.
2) American refrigerator.
The sad part of the trip was we flew back just as they upped security and went from X-rays of baggage to MRI units. All the video we had taken on the trip (often instead of photos) was totally wiped out, including her last memories of her grandfather.
Thanks terrorists.
