What do i need to take to go carp/rudd/roach fishing?

You tie your rod to the cross-bar of your bike as we all used to do when we were young. You will of course need something to sit on and hopefully a landing net. Do not forget that you will need a rod licence (Post Office) AND the permission of the owner of the fishing rights. When you want to catch carp you will need specialist tackle, I would suggest you start with the roach and rudd unless the carp are small.
