It was my understanding that it was the vinegar that makes the rice
turn hard over time. That is why the rice is kind of crunchy when you
eat a left over roll the next day.

Yeah --- I was thinking maybe the vinegar would keep it from spoiling.
Fresh is best, for sure.

I just learned another lesson about preparing rice -- if it's too dry,
forget it --- the rolls crumble. Thats fine. Live and learn.

Since I will be kayaking solo --- I will try to catch small fish so as not
to waste the meat also. I will have no way to refrigerate/freeze and I
suspect sashime does not stay fresh for long.
