Ok, put the rubbermaid box in a large plastic pack liner. Roll up the top. You can get these from camping stores or from outfitters. Put it all in a Tripper pack made by Camp Trails. Cinch all of the straps tight, and voila an odor proof food box. I've done it this way for years, rodents or not, nothing has ever bothered the box using this system. And I don't have to waste a good hockey puck either. I've never hung a food pack.(bear pinata)  I have had bears checking the trees looking for it however. The straps are on the Camp trails pack.
