So last weekend the wife and I got a huge jar of pickles at Costco. The thing is bigger than a gallon of milk (the wife really loves her pickles). There really isn't any room for it in the fridge, but no where on the jar does it say 'refrigerate after opening', but I've always kept them in the fridge (and so does everyone else I know).

I know that pickles use to be kept out of refrigeration in barrels and I realize that the salt in the brine should keep anything bad from happening, but does anyone actually keep their pickles at room temp? Are there downsides to this?

Thanks
