Moreover, deck surfaces on a boat can get pretty hot, and it doesn't take long to cook those worms if you forget to put them in the ice chest.
FRABILL's Crawler Can is an insulated plastic can with two lids — bottom and top. The bottom lid allows ice to be packed in the container, while the upper lid opens to allow worms to be stored in a cool compartment throughout the day — even in the hot sun.
We never baked a worm on our outing along the coast. And, the ice at the bottom lasted the entire time we were on the water.
