Buy a cheap 5 ft net at wall mart and go to any boat ramp early..or preferably one that is closed...much easier than relying on someone else and you know yours is fresh...it's easy buddy...u can do it! Once you get good at throwing you can move up to 6 or 7ft.... There are a few shad salesman here on tff so someone might chime in if your dead set on buying bait..if your in a boat then throw your net around bridge pilings out in deeper water.
There is a fine line between fishing and floating around like an idiot!!
