Ok so you have to live one day over and over again! Which one will it be and why?

I was watching Groundhog day AGAIN! and started to wonder if there was any particular day I would like to live again. Not just a bad day in which I could change bad things from happening, but also a good day, when I had a fabulous time and would enjoy re-living over and over again! Like my wedding day, I will never tire of that fabulous feeling knowing that I was marrying the man I loved, and the day my baby girl was born :)

So what day would you like to re-live over again and again? Either to change something from happening or to re-live a happy time?
