I had i go at this once (beach casting). I think you can set yourself up quite cheaply to start with. Best advice i would give, is to find out where all the beach, or pier fishing is done in your area, get down there and talk to the people actually fishing. Like has been said, they are quite a friendly bunch and will let you know all the places to go, and the tackle shops to use. Think one of the drawbacks, unless you can dig them yourself, is the price of the bait. Having said all that, it's a great day out when the weathers good.
