Woods Walker, you are right on the mark as to the real reason why we use blue barrels these days.  It really isn't bear control, (although we do separate the barrels at night to prevent total thievery) it is more to keep the mice and squirrels at bay.  Over the years, we have had more issue with mice chewing holes into otherwise good packs and spoiling food.  No more with the blue barrels.  I also echo your idea of a clean camp.  No dirty dishes at bedtime.  I don't want camp swarming with mice and other varmits (including bears) licking the plates, pots and pans.  

We use the blue barrels exclusively for food.  In camp, we have a mesh 'dish rack' that we use to hang and store washed dishes where they hang and dry and are easily accesible.

Anyway...
