I picked up about 20, 5 gallon buckets from work this week,their washed and clean. I was wondering....? Do you think that just drilling holes in them, and filling them with a little gravel and sinking them would work? I know it would be better with stakes or pvc....but I was thinking that these twenty sank roughly a couple feet apart would look like a stump field....There is a lot of natural cover in this lake...I'm thinking of sinking these on a flat that is void of cover in about 15 feet of water. What does every one think..???
