We grow our own tomatoes. The bonus--they actually taste like tomatoes, unlike the cardboard tomatoes you get at the supermarket.
You know, don't you, that we got the cardboard tomatoes when the last guest worker program went away, and the growers had to find a tomato sturdy enough to be picked by machine.
There may be Americans willing to do the job, but not enough of them, and not reliably enough.
Fresh peas are already rare for the same reason. What produce will we lose next?
