Yeah at crappie camp I was like...yea...they'll live for a week or so....oh no...they lived a LONG time...I was amazed. He also did this in the summer time...but they would diffentatly last for a weekend. lol. He used one of the extreme coolers you can get at walmart. The main thing he said was not to let the ice contact the bags...he also said make sure they put the pill or shoot some air into the bags...ice/towel/minnows...and that was it. :D
