Yeah I'm probably on the high side in my numbers but 10 primary schools a week should be quite achievable, along with a visit to the children's hospital and some form of community appearance every now and then it's not rocket science.
I recall when I was younger and the Sydney Swans sent a few players to our school ahead of pre season game at No1. I was given free entry to the game that I had never given thought to before and went to it. After the game I asked my parents if I could play AFL for one year an the only thing that stop me playing was the closest team was in Warners Bay which was 20 mins away and my parents convinced me to stay with my local Football Club around the corner.
