The issue focused on how much water you would need to walk to your goal. This may not seem like a lot, but you would need to walk for more than 3 hours to reach the target.

In this study, some rules were used to ensure that I would not get too far off course. I would only need to walk for 3 hours to reach the target, and I would also get to the study area for 3 hours. I would also get to the study area for at least 2 hours.
