When I was growing up in Finland, there were a few sure things that happened every year around May day.
1) People got hugely drunk.
2) There were balloon vendors everywhere. I seldom got a balloon!
3) It usually rained.
4) Communists had a parade with red flags and singing songs praising The Soviet Union. Our family would go and watch the parades.
5) My mom wore her high school graduation hat (yes, it is a tradition still today).

6) Donuts and "sima" (citrus drink that had been fermented) were plentiful.
7) Funnel cakes were yummy.
8) Happy people walking all over the city (if it happened to be a sunny day).
9) A Men's choir singing on the steps of the city hall.
So, what tradition did I bring to this country?
Yep, you guessed it...
Donuts. Made them yesterday. This morning, hardly any left.
