Morning Carel,
I am on my way to Simba Lodge Ikoma, so I had the chance to drive through the herds today, I bumped into big herds at Lakes Ndutu and Masek with the Ndutu Triangle packed with scattered herds throughout the plains towards Naabi and Simba Kopjes, some more towards Moru and I can imagine to Kusini Plains.
We also have reports of herds towards Gol Kopjes towards the east. Lots of water and new grass so not much movement on a daily basis, I think this is as close to wildebeest heaven as one can get.
Keep well,
Ephata
