(Tetra Images/Corbis)While out walking recently, my partner and
I saw an admirable stand of rhubarb. The homeowner happened to
be out in the yard, so we complimented him on his green thumb.
"Feel free to take as much as you want," he said, with something
like desperation in his voice. Seems the rhubarb came with the
house, and no one in his family eats the stuff.  We cut 10
pounds' worth of stalks, and you could hardly tell we'd taken
any. Right now I'm out of town but when I return I'll knock at
that door again. Later this summer he'll get homemade raspberry-
rhubarb jam as a thank you.  The raspberries will come from
several feral patches I've scoped out in the neighborhood. I
also hope to pick wild Alaska blueberries and lowbush
cranberries (aka lingonberries). B
