For me it was the 26th annual WrestleMania and it was hosted in Arizona where I live which made it a very special event for me to watch. The main event was The Undertaker Vs. Shawn Michaels and The Undertaker defeated Shawn Michaels by pinfall which essentially saw Shawn retire.. but yea it'd have to be WrestleMania 26 for me for those reasons alone.
