I agree with this pair, not that I have kids or been in the situation but it often looks like more of a day for the parents to say my son/daughter went to their first Derby game, not the kid itself.
Back and forth making the entire row stand up so little Timmy can have his 5th bag of crisps to keep him quiet so you can watch the game.
Must have been 8 or 10 when I first went, possibly a little older, I remember very little even at that age, middle tier of one of the two ends at the BBG, freezing cold and chips on the way home. Couldn't tell you who we played, the score or anything.
Now I'm not saying every kid has a memory like mine, but some kids I look and think they have zero interest being here, would much rather be in the park kicking a ball about themselves.
If one day I end up with a kid, will be a bit of football on the park, see if they take to it and on TV, if so and like Cosmic and iRam say start asking to go, not once but weeks and weeks, I will then consider it. If they decide football isn't there thing I'll be just as happy.
