I just noticed the black walnuts have started falling.
I'm wondering if I should bother harvesting and shelling
any. It's been decades since I did, and I remember them
being difficult to crack (hard, thick, nearly spherical
shell) and pick the meat from. Lots of work for a little
mound of black walnut pieces. As I recall, they have a
sharper, more concentrated flavor than regular walnuts.

Somebody said you can dehusk them by driving a car back
and forth over them. I didn't have a car back then,
but I do now.
