Here is what happened. My wife & I were students living in Pullman Washington and we must have somehow used-up too much of this box to leave enough for another meal. If it had been spaghetti, there would have been no problem--it would have just been combined with the next box of spaghetti. But we didn't often use linguine and I don't like to combine different shapes because then some of it is either over or under done.
We baked a lot then and ever since, and so the box became our source for done-ness testing probes--you stick a toothpick or spaghetti noodle into a baking cake and see if it comes-out dry.
This box made a meal in Washington and provided probes for baking in two homes in Vermont and one here in Massachusetts. Now it is all gone. The end of an era and probably the only foodstuff we still (until about a week ago)owned from our first year of marriage.
