I read a post, I think the guy that posted it said was in an issue of Louisiana Sportsman, about using barrels and buckets, etc. for different age and size fish and placing them in a 60' to 80' diameter circle. The barrels had different size holes cut in them for different age and size fish. I believe he said you put gravel in the middle of the circle and pvc trees. I saved the post and bookmarked it, but now I can't find it. I did a search but could not find it. Would someone please point me to the article? Thanks.
