I thought I had some pix with out brush but I don't. We have some over-pack drums. I have used regular 55 gal they work just not as comfortable. All we did was dig the holes in the marsh and fill them full of water them drive 3- 8' 2X4's and lag bolt them to the barrels. Never had one pop up in 15 years. Here is a pic of how it looks all brushed up.
