I was shown how to catch carp there with mielies haha

Go to the top canal accessing from m5/most north marina entrance, find your way to the canal that past you feeds into the vlei, a brak canal with houses will be on your south. Chuck a handful of mielies against the far side of the canal away from you (north side), rig your line with a van der merve hook, nothing else, no sinkers, swivels etc.. Put as many mielie kernels as you can fit on the hook and cast it against the opposite side into the same place you threw the corn earlier. Leave your drag loose so a fish can pick you up and run with no resistance and wait.
Shouldn't take too long. We used to have serious compos with buckets of KFC at stake and used to rack up serious numbers of big carp and I saw my old fishing mate recently and he says the carp are still there, fat and plentiful as ever. In those days you could put a livie out on the south side of where you sit and we had a few double ups with big carp on one rod and leerie on the other and guys running up and down the little arm of land and folks watching the madness curiously from their lawns, dogs barking from across the way..Good times.
If you don't come right go ask the guys at eddles for advice, I know one chap in particular spends quite a bit of his free time down rutter road.
