Totally disagree. Depends on the kid.
At 6 years old i had a season ticket and was begging to go to Away games. Can remember going to the likes of Firhill, Somerset, Cappielow and Kilbowie to watch us and loved it.
My mates wee boy is 6, is football daft and has had a season ticket since he was 4. Loves going to games, especially aways where there's more atmosphere.
