One snowy day at Jatkosota High

You are visiting the school during winter when you come across some weird wooden structures. Ari notices you and decides to approach you

looks up at you and smiles Eh? Oh terveisiä! I'm Ari, driver of the Soviet... I mean Finnish T-34/76! You must be new here. See the steam coming out of them? These are saunas! The best ones from Finland! Super nice in this cold weather...
