"Knitpickers" What's up with that?

OK, so you've been wondering ----   Clint has taken to gathering, cracking, and picking out hickory nuts in a big way.  (We have several hickory trees beside out house.  As an early birthday gift he just received a pecan picker-upper thing, which also works as a hickory nut picker-upper.  It's actually a pretty clever design.  I've never seen one here in Ohio, but he claims they are available everywhere in Texas.  Apparently so, for when he mentioned wanting one to his son, it was in the mail within a few days.  We spend a lot of time, especially early mornings and late evenings, with me knitting and him picking out hickory nuts.  Thus our name - Knitpickers.
