Keep them outside in an open air container-coons will love you! Smart to fish opener on Monday BTW. Keep them cool and avoid fast temp. changes. I would put the bag in the fridge and add a plastic ice block to the continer when you go out. Good luck
The oxygen filled bag from the bait shop will keep them healthier than an open air container for a couple days. If you can’t keep them in the fridge I’d put them in a cooler with ice.
