Jabbo you are right this is what my father told me. Take a wet towel or damp place on top of the crawls in some thing refrigerated hope thats spelled right but any way come back in a week or few days to see if there soft. I have personally never tried this before, but one time I stopped at a bait store and asked how much for the soft crawls and the price was 9.00 bucks a dozen for that price I think I might catch my own.
