All three of my uncles served in WWII. All have since passed away. My dad wanted to serve, but kept flunking the physical due to a duodinal ulcer. He was a scoutmaster, and he set the scouts to work selling $70,000 in war bonds, planting victory gardens, and collecting materials needed in the war effort, such as scrap metals, etc.
He passed away in 1995.
The war effort could not have succeeded without service on the home front. Your father's efforts should be commended and remembered.
