These days you seem to be able to buy all sorts from a vending machine, but this one at Potter Heigham takes the biscuit, or rather it dispenses the bait. Lovely fresh maggots, white, red or mixed. Take your pick. I suppose they must sell quickly or you would get a worthless packet of flies. In case you are wondering, the current price of maggots is around £2.70 a pint. When they turn into chrysalids, which anglers call casters, they cost a quid more. Don't say I never teach you anything!
