Unfortunately, there is no such thing as paddling upstream slowly. This is especially true when your idea of paddling slowly is to take three paddle strokes and reach for a Dorrito. After about a month of this you've whisked past Hartney and have entered the sandhills area near Lauder.

Fortunately the current becomes even slower and you begin to make progress, even with your "relaxed" approach to paddling.

You camp for the evening near the site of an old fur trading fort, after pulling the canoe up to a sandy bank. In your haste to start a fire and look for an outlet so you can plug in the microwave , you forget to tie the up canoe.

When you awake it is nowhere in sight.

What should you do?

You could run along the banks, and catch up to your wayward canoe.

Or you could give up the whole project. If you hustle you could be back home in time to catch the afternoon re-runs of The Big Bang
