you can redo them, but I never did. Long term storage is how they are to be most useful. But, we never seem to keep stuff around too long! There’s always fresh everything available here every day!
on a side note.... another side note... while waiting for Trump...I am sitting here listening to my frogs down in the pond. I love listening to them, even better than crickets! I wonder how they can reappear so quickly after the snow melts in the winter and after a rain in the summer when their pond gets refilled.
