I buy beef, pork, chicken and eggs from local farmers.
They also have seasonal vegetables and even store and sell potatoes, onions, leeks, etc.. through the winter
So it seems Americans are perfectly willing and able to “pick the crops” — especially when they own the land, can support their families, aren’t harassed by government, and don’t have big Agri or Walmart in the middle.
I just made a rhubarb crisp from frozen Rhubarb I picked from my garden last year, it was wonderful.
