A bit off tangent, but hoping one of you can shed some light on this. . .
I did a year-long exchange program in Germany as a high school senior in the early 90s (Parlamentarisches Patenschafts-Programm) and met an uncle of one of my friends, who had a distinctive vertical scar on his face. Was told that he was in a "dueling society" and it sounded like it was received in an initiation rite as opposed to accidental mishap. I asked a few other Germans about it later on and got some disapproving vibes. This friend was from a very good family near Tuebingen, where I started my year and I know they were all hunters (sadly I did not get to experience that during my time there).
Thanks for any insight-always been a bit curious about this,
Bill
