I'll list a few....
My first time at MGM, catching the perfect picture of Jiminy Cricket, who was my favorite character before Stitch came into existance.
Having the animator CM on the Animation Tour draw us a Mickey head and sign it for us when we just asked for her autograph. We have it framed. It was and still is our coolest souvenier. It's just a shame that she did actually make it inside the studio as an animator only to be dumped by Eisner's bad anti-2D animation policies. But, in our hearts Jen Kagel is a wonderful lady.
My first time meeting Mickey at age 34 and crying like a baby because I got to hug him. I waited 30 years for the chance to do this, since I didn't get to when I was 4.
Seeing Gabby, my partner, interact with Lilo & Stitch when Lilo hit Stitch, Gabby said, "Don't you hit my Stitch!" and shielded him. This from a 29 year old woman who was dead serious about keeping Stitch safe from further harm. Her reward was a booger that he picked just for her. lol
Some wonderful interaction with Chip & Dale at the Ice Cream Social over at Epcot. Let's just say that leaving the backpack open for them to grab stuff out of was worth the show.
Walking up Main Street in the "snow."
Seeing Wishes for the first time.
Riding BTMRR as the fireworks were going off and having become a whole new ride as the fireworks burst right over our heads. It was just too awesome!!!
There are so many more, but these come to mind right off. Maggie
