My grandfather had a country store and he also sold bait to local guys. Had a fridge turned on it's back filled with manure raising red wrigglers, had a big plywood box with lights and a screen top to raise crickets, and he kept a barrel with sawdust in it for the meal worms (golden grubs he called them). Kept them covered with newspaper, and dropped a half a potato in once a week. They ate the paper and got their moisture from the tater. Sold them for fifty cents per 100. Lots of memories.
