Since legs usually take place every other day this season, leg 6/7 (we don't know if Vietnam was 2 legs with a No-Rest Pit Stop or a Mega leg with a fake Pit Stop) probably started today. If we don't have sighting by tomorrow, then I believe they're somewhere rural. Whether that be Europe or Africa, I don't know.
Hopefully, we get something soon. I hope for an African country that has never been visited and/or an African country that hasn't been visited since the early days of the Race.
