Traveling to watch your team play at the opposition's ground. A pilgrimage. Involves early trains, service station breakfasts, and standing in the rain in a corner of someone else's stadium. Away fans are universally considered the best fans because they've made the effort. The songs are louder, the atmosphere is more intense, and the pies are always worse.
"Six-hour drive for a Tuesday night match in the rain. That's a proper away day."
