Karma Laundrette

I buy a plastic-y turkey cooking bag, put it in the cooler, put the turkey in the bag, then pour 3 gal. brine (same ingredients as your recipe, basically, in 3 gal water) into the bag with the turkey (this is a two-person operation). Tie the bag closed, then fill the rest of the cooler with ice. Close and stick outside in God's Fridge. This way I can get the turkey exposed to a uniform brine, keep it safely cold, and still have room for something else in my fridge.
