Every avid fisherman knows that the most valuable thing for a fisherman is not today’s catch which can depend on many factors independent of the fisherman but knowledge of the places where fish are a priori found.
Such fishing spots are usually kept strictly secret but every fisherman wants to trick another fisherman into knowing about the fishing spots.
It's funny on the one hand you are hiding a secret but on the other hand you want someone to reveal their secrets to you.
But don’t burden yourself with this the fishing spots themselves as practice shows are located on the market in the fish department and the best bait is cash.
