How to catch carp?

There's a guy on another forum I visit that's trying to catch them on 2lb test for the record or something. He says he just uses white bread, balled up around a hook. No sinker, no float, just let it float on the water. I haven't tried it, but he swears by it.

you might trying baiting an area and then going back later. you can use corn or just make make balls with white bread. use about a half a loaf of bread or a can of corn. then go back in a couple of hours and use the same as bait.

What's the best time of year to catch them? Spring? Seems like that's when we blindly caught a few and the fight is tremendous!
