This is very weird and random, but travelling to USA with my friend to watch the Michael Jackson trial in 2005.. I'd been a huge fan of his since I was a young girl, and my life long dream until that point was to meet him or at least see him in person.
It was an amazing experience, I got to meet some incredible people, including his cousin who took us to Disney land which was so much fun, I didn't meet the man himself but sat in close proximity to him in the court room on several occasions. A very weird circumstance under which to see your lifelong idol, but still 😆
Other than that, most of my best experiences involve travelling and snowboarding.
