Biden has several times promised he will go to Africa, without doing so. His October 2024 trip just got "postponed", and he promises that it will happen. Will his term come and go without it ever happening?

"First visit" from market start, of course.
As reported by credible media.
Will be resolved by first day he sets foot on the continent. Multiple trips or countries do not matter, will only resolve to the first one.

Local time in any country he sets foot in.

Set to "any number" so that periods can be resolved as they pass, and not lock up mana.
I expect to bet in this market, resolution seems unambiguous enough.
