My college son hit a walk off HR in today's game. He gave it to the local second grader that was hanging around after the game and they had their picture taken together. That's what warms a mom's heart. Priceless.
When my boys were younger we would go watch free baseball at the local college nearby. We would sit in the outfield and they would run for those home run balls. One game a dad offered my son $5 for his son's HR ball. My son looked at me in shock when I said nope, and hand over the ball to the dad.
