I live in U-City but have never heard of it. You might want to contact the historical society -- they're often accommodating in digging up old articles and photos. http://www.ucityhistory.org/contact-us.html
If you get any pics, please post them!
I had to look up Sisu - great word describing the very essence of Mika.
For those not familiar, according to Wikipedia: “Sisu is a Finnish concept described as stoic determination, tenacity of purpose, grit, bravery, resilience,[1] and hardiness.[2”
