So why did our packs weigh so much this time out? Here is a good reason why. This sandwich is made with fresh avocado, bacon, colby jack, and a bagel. Being in the woods for this long you learn that many of the items they say need refrigeration actually do not. Cheese can last for days even up to a week. Apparently bacon can last a few days as well. We even have a friend hiking with mayonnaise for up to a week. Don't believe the hype most food can last for a few days out here if the bears don't get it. Wait, how long does it take for the symptoms of botulism to begin to appear?
