I am an avid fisherlady,with my son. We go once or twice a wk ( sometimes more). We always have a bunch of ***

ht crawlers left. I'm wondering if we can save them for the next trip? We buy them in a small container and they are packed very tight in there w/some black dirt. Usually they are dead by the time we go again. We put them in the fridge until it's time to go again.Any suggestions?
