Informative for sure. Sounds like there are a few corruption concerns if I read the translation correctly?
Translation might be confusing sanctions with corruption, it wasn't mentioned.
The main thing is that Rotenberg + the three others are on the sanctions list, meaning the US isn't meant to do business with them. Having NHL games in an arena owned by their company doesn't look good.
Have you been to Hakametsä? It's horrific
Once on a trip with my soccer team, 2002-ish maybe? It was a local derby where Helminen broke the record for most penalty minutes in a single game (which has now been surpassed, I think). We sat behind the penalty boxes about halfway up.
As I already said, Turku might be the best alternative if Hartwall is a no-go. Look on the bright side, our Swedish comrades would have an easy boat journey to the game then, the arena is a stone throw away from the harbour from what I remember.
