Life .
Mine was back in July 20th 1969 .
Most people had black and white TVs millions all over the world saw Neil Armstrong jump off and make his leap for mankind
And of course Aberdeen winning the European cup winners cup 11th May 83 .
What about you fellow posters ? 
Add to this my children coming into our lives that was amazing experience.
Going to the UEFA cup final in 2008 was pretty special, even though we got beat.
The Twin Towers coming down will always live in my memory, I watched the news live as I was dogging school.
This wasn't in my lifetime but I'll mention it anyway. On display in a hotel on Arran is a handwritten account of when it's electricity was initially installed and lights first turned on. It was an exciting moment not just for the owners of the hotel (who were ancestors of mine) but the village and surrounding farms as a whole. Nowhere else nearby had electricity.
Like you, my child coming into my life was an amazing experience, as was getting married in our traditional service. Yes, I'm a soppy git 
Dogging school?
