Hi Carel,
Yesterday we were lucky to witness a mega crossing at Mara River main crossing point, over 50,000 individuals crossed over to the Mara Triangle conservancy en-route back to Serengeti.
We could hear thunders and rain clouds forming down south (Serengeti). These are the herds which were feeding at Musiara marsh area (Northern Mara).
Regards,
Onesmus
