Hook
Have you ever carried a bucket of water from a stream to your garden? Have you ever filled a big pot with water and carried it to the stove? Have you ever carried a gallon jug of water home from the store? What did you notice about carrying water? You bet. It's heavy. Think about how much water you should drink in one day, at least 8 full glasses. How much would you need for 100 days. Wow. If you're skiing across Antarctica (2,400 miles), would you want to carry that much water on your sled? Could you? Remember you have to carry everything you will need to survive with you. Where are you going to get your drinking water, that water you must have to survive?
