Hi Carel, from the Serengeti side, there are some massive numbers in the Lamai and Northern Kogatende area, I had a look north of Kogatende as well , past the Mara river, they are spread out, chilling on the plains. Also a few near Grumeti on downwind side of runway 11. Think most of them are in Masai Mara again. One of my photography mates saw massive crossings there in between Musiara and Mara Triangle – keep well and we see you soon, Joel
