I will direct the crew and the ship to the North Pole. I want to try to reach the end a border of the North Pole to the other end and explore its extremity. It will be dangerous because the ice I might be walking on can be is thin ice. I might also need to climb on a glacier. But, the glacier can float the wrong way. There is almost no people living there (except my crews). But, I still want to try it.
Sailing to North Pole can be dangerous, too. My ship can hit an iceberg and sink like theTitanic or we can sail the wrong way and end up in the South Pole. If I landed at the middle of the North Pole, I need to walk to the end border. That will be harder than just landing at a borderline. If I land at a end border and I am walking to the other end border, and if my compass went wrong, I could end up on where I started. But, still, I want to sail to the North Pole and walk from the end borders to the other border.
