Enjoyed your reply. Europe is a great place to take your son or daughter to appreciate the other worlds on this planet.
When my son was 10 and playing little league, he insisted on taking his bat, ball, and glove on our trip to Germany. After our daily tourist trips we'd come back and pitch and hit on a soccer field. The local kids came around to watch us and soon joined in. They didn't have gloves so we made a soccer-baseball rule. If they can catch the ball on a one-hop, it's an out. Those kids used their feet to kick the ball up after hitting the turf for a catch and a 'fly-out'. It was a kick watching them.
On his own, my son decided to leave his ball, bat, and glove with his new soccer friends in Bavaria. It was a nice gesture, but I don't think they'll be starting little leagues in Germany any time soon.
I guess it depends on where you are. When I was stationed in Wiesbaden (1997), there was a German team that played in my kids MWR little league.
