The Great European Scavenger Hunt

For my graduation present, my mum is taking me to England, Germany, and possibly Austria and maybe Iceland, so I am creating a scavenger hunt of all the things I want/should do and see while overseas. The problem is, I have never been so I need some locals or frequent travelers to help me choose some cool stuff!

So far I have:
-Find a Kinder Egg
(They aren't sold in the States and I've always wanted to have one)

-Sing songs from the Sound of Music in Salzburg
(because it's one of my favorite musicals)

-Ride my first train
(Another wonderful thing the US doesn't have very many of)

So what other things can you lovely people contribute to my list?
Please comment or send me a message!

Thanks!
Ashton
