I used parts of my front yard : one side of the driveway for the tomatoes, and the other for a salad garden.
to me it was fine. once done, you won't regret it if you get the best sun there.
that the front yard is for The Lawn is something that developed after WWII in this country.
there was an interesting book published about this some time ago more or less called The American Lawn
vets came home from the WW, got GI loans and small tract homes think Levittown and the Lawn developed
at least that's how I remember it.
should have been the Tomato Patch. Tastier.
