Yes, I believe so, NyBoy.
If you go back to the beginning of the "foreign" wars, half the American civilian population was on farms. People had use for children and when the young men went off to war, the ability of the nation to feed itself and them was compromised. People were encouraged to grow as much of their food as possible.
I have a picture of my mom in her newly-planted victory garden (i'll look for it). My grandmother's garden in Canada was in the shape of a "V" even tho' she had all sorts of room around it to make it any shape she wanted. It was the '60's before I saw it and hadn't been cultivated in about 15 years but you could still see the outlines.
