I was just thinking last night as we were driving home from my husband's work (he cut my 55-gallon barrels in half for my garden) and I was going thru his bag that I keep in his truck. It has a change of clothes (he tends to get dirty at work) and a few other essentials... and I thought... I wonder how often I need to change out the bottles of water, energy/protein bars inside his bag.
Now I see your post... I take it as a sign to rotate some stock in our travel bags.
