Back in the 80's I use to go to theCamden Grain Plant which was close to the Budweiser Brewery. They bought all the waste from the beer making process and sold it as cattle and hog feed.

You would have to take your own 55gal drums to be filled and it was $10 a drum. That was the best hog attractant anyone could buy.

When the brewery was closed and moved to Jacksonville, Camden Grain closed down too![:@]
