Very large group between Seronera and Lobo

Serengeti Migration back-end update Hi Carel, I flew in from Arusha this morning to Kogatende and there is a very large group between Seronera and Lobo, they were well spread out and not on the move. Puts them 40km south (as the crow flies not as the wildebeest walks) from what I could see of the Mara River on approach, no activity on the river itself. It seems they will be at the river when you arrive next week, how did you know? Regards Mark
