Last Monday, I was at Lombard Commons Park playing disc golf. After finishing #3 (point A on the map), I heard a noise about 25 feet behind me. The person playing #3 had a large dog snapping at him (point B on the map).
I called out to the people watching a softball game involving 7 year old girls (point C on the map) thinking the dog was with one of them. The dog turned away from the person and came after me. Fortunately when I hit it in the face with my disc golf bag (which had about a dozen ones in it) it backed off.
At that time a woman (point D on the map) who was walking from the street that ended near where I was called out to the dog. It saw her then ran away with the woman walking after it. (arrows)
After playing the next three, I heard police sirens at the ball field at the other end of the park. They caught the dog in short center field (point E on the map) interrupting a different softball game played by 8-10 year old girls and had a police vehicle there.
While I was waiting to play #6 (point F on the map), the woman who was talking to the police pointed towards me and the police waved for me to come over by them. She was upset that I hit the dog with the disc golf bag even though I had seen the dog snap at another person then go towards me. The person who was behind me 15 minutes earlier confirmed my story and to my surprise and objection, the police let the woman go
home with her dog
