just go to Kroger or any local grocery store and ask the seafood department for there old shrimp that has gone bad . I can usually haggle them to 50 cents a pound since they are gonna throw them away.

and for chum I usually by a whole chicken or what ever they have that has spoiled for a couple of bucks and drop it into a 5 gallon bucket with a pound of Milo and Maze or any other grain and let this setup in water for 4 days . Every other day leave the lid cracked for a few hours and then replace .

After the 4 day DONT!! open it till you get to where you're fishing . I will poke holes in the side of the bucket and wade out into the water or if my boat is wanting to run I drop it in about 10 feet of water with a anchor of some sort . This chum works and smells so bad you will probably end up puking at least once the first couple of times you use it . but the good thing it last a while if you poke small holes .

I have hit the same hole on lake Arlington for two weeks and the area that I have placed the chum has produced fish.

Good luck and I hope this helps .
