A day in the life of “my Papa” as seen through the eyes of the 4th generation…

Rick Lee Senior’s 11-year old granddaughter, Kirkland Miller, wanted to tag along and see what a day at work is like for her Papa. Kirkland, who has a passion for creating videos, enjoyed shadowing her Papa and seeing the Affiliated Steam office through his eyes. This shared experience shows a great perspective of a work day at Affiliated Steam! Thanks, Kirkland!
