Great advice, Trish. I hadn't thought of that. I'm writing down that on my list of things to take. I use Crystal light tea mixes and when that container is empty. I save it for storage. It holds my plant markers. If I make up a plant ID marker and for some reason I don't use it. I just stick in back inside the empty container. You might use it at a later day and if you don't. just lay out on newspaper in a well ventilated area and spray paint it another color for future use. Recyle!
