Hey there Centerdriver,
I have heard of a guy using fishing line and tying it off to the hole made by the hook and using a small balloon to keep up with the fish. I have saved a few gallon pickle jars for the minnow trick but as of yet haven't tried night fishing. Good tip about screen over the jar.
I really like reading about the tricks used by some of our grandpaws back before we had some of the equipment available to us today.
