you take about 4-6 kernals of sweet corn hokk them on your hook, place a cople split sots 12-18" up your line and cast out. Then you just have t wath your rod tip for movement, the current of the rive will allow the corn on your hook to move around the 12-18" you gave it. dont know why they like it but the rainbows and brooks inhale the stuff around here. ad in still water you simply put a float on your line and cast out havong the corn b about 4-6' under the float. If you think im B.S. ing you ask your self why did berkely makea "corn" power bait this spring. but i swear by the stuff. i think part of the reason it out fishes other baits is that it is so smelly that the ois seep out and the fish can smell it from a long ways away.
happy fishing, Ben
