Good posting Mark.
RE WW2 my Father was based at Heston aerodrome he worked on spitfires, but never left the country, so no interest to me.
I did visit Poland with JY many years ago and have witnessed first hand the horror of Auchwitz and berkenhau, it was something I wanted to see and having seen it once I don't want to repeat it. When I did the Poland tour the concentration trip was optional and NOT everyone wanted to witness the horror. We also stayed at the Tatra mountains which were beautiful!.
