HKM Engineering

I have worked at an engineering firm in Billings during my school breaks for about 5 years and they have always been wonderfully supportive of me in my schooling and my Miss Montana ambition. They asked me come and sing for them before my reign was over. On June 5 I talked about my year and how it was coming to an end quickly. They enjoyed the songs and were quite interested in what I did as Miss Montana. Now can anyone tell me, when was the last time Miss Montana officially appeared before a roomful of engineers?
