In rugby circles, the year is immediately synonymous with the All Blacks' World Cup triumph.
But in Canterbury circles, 2011 triggers very different memories. The quake.
And in a region that spent the first part of this century drip-feeding the All Blacks with our country's top rugby talent, the 2011 Super Rugby season was one where barely anyone attended a game.
AMI Stadium was ruined and the Canterbury Crusaders spent the entire season on the road. From Nelson to South Africa to London's Twickenham, the Crusaders travelled more than 100,000km.
Their success in 2011 was special. They made the Super Rugby final against the Reds in flood-battered Queensland and were nominated for the Best Comeback in the Laureus World Sports Award.
The devastation in Christchurch that year put the oval ball in perspective, but the brave crusade led by McCaw and Carter provided a critical weekly diversion for the red and black masses.
No matter their standing in greater New Zealand rugby history, Canterbury will forever hold its favourite sons that much tighter.
A special World Cup edition of the Herald on Sunday will be available at selected Auckland retailers mid-morning today.
