To me, I've always LOVED training camp. So many players working hard for the chance to make the final cut for the team. Or, try to show enough to possibly make it on another team. Always amazed at just how fast these players are when you get to see things at field level. I'm still amazed at the speed and the vision they have to see things develop at the line of scrimmage.
For the kids, its always fun to see the faces of the players they see on TV. Or even get a chance for an autograph or two, or actually meet a player. The activities for kids were always fun too. Several years, I probably missed more than half of training camp because the kids were having so much fun doing all the different activities they had on hand.
