Pacific legs can be 20+ hours, and there are some people who have done 24+ hour legs in single engine planes.
If you do more ferry flights and build a reputation as someone competent and professional, you will get to see airports like Iqaluit, Sondrestromfjord, Goose Bay, St Johns, Bangor, Reykjvavik, Wick, etc. Maybe you can run into Tom Danaher if he is still doing any ferry flights. He is quite a character, having flown in WW2, and if you dont who who he his, you have seen his work in many movies.
At some point, hope for a breakdown in St Johns. Spending a couple days there is not a hardship at all

Well the hardship part will be getting up to go fly after a night on George St.
