2011 gaa all Ireland football final.
Emotionally, for me, it was huge. Me, my dad, and my sister went to every Dublin game, we won the Leinster's most years, but never the all Ireland.
Me and Riona had to sit separately from dad, because the only tickets left were that way. When Clucko took the last kick, we RAN up 5 flights of stairs, and he was running down them, we just about made eye contact when we heard the Dublin roar.
It was the last game we ever attended together, he passed away the next May.
It was also a fecking excellent game, and anybody new to GAA I'd recommend watching this
