My first Disney memory is of the fireworks at Magic Kingdom. I was really really young - 2 or 3. My dad was in the habit of putting me up on his shoulders a lot of the time (i was a skinny little thing), and he put me up on his shoulders to watch the fireworks at park closing (I believe this was 1981).
I loved loved loved Disney and went all day without a stroller, he put me up on his shoulders for fireworks, and I guess I fell asleep. My memory is of waking up with my head on his shoulder - I remember I picked my head up as we walked up the monorail ramp, looked behind us, and I could see the HORDES of people behind us, leaving the park. It's probably one of the most peaceful memories I have, leaving a place I loved and in the arms of my dad, who had a job that made it so he couldn't be around too much.
Funny enough, my very FIRST memory is of a Mickey Mouse punching bag (one of those you blow up and then punch, and they fall down) and another Mickey toy that's hard to explain. I was probably around 1 year old, according to my mom.
