If you want to get really fancy, take a 3-4 foot section of 6-8inch metal pipe. Weld on a cap on one end with a section of chain, and use a threaded cap on the other. Drill with some 3/4inch holes sporatically - not swiss cheese, but say one every 6 inches randomly around the pipe. Fill it with your sour corn - earlier recipies work fine, grape koolaid is a favorite additive for me. Screw on the end cap and secure the chain to a tree or t-post.
PVC will work for a while if you want to test it out, but they will destroy it eventually.
We've used them in Texas - a lot of fun for night hunting in particular - you will definately know when they come in. Esp fun if you have a spot near camp that you stalk in to in the dark - you can hear it from quite a ways away.
