That reminds me of the nights we enjoyed hunting with Spear Safaris in June. We had lions around our camp every night, and they did quite a lot of roaring. For me, that was a lighlight of our trip.
The first time I ever heard lions roaring at night, we were hunting in the Chararra concession in Zimbabwe, just east of Kariba. One night, we could hear lions roaring from very far away, up the Chararra River. They kept getting closer and closer, until we heard pots and pans go crashing down in the camp's kitchen! Everyone in camp was awake (obviously) but nobody was going outside their tents at 2:00 AM. MY wife and I were in our tent, and suddenly, I could hear a lion walking just a few feet away, on the other side of the canvas. They were heading up the hill to our buthery, where a cape buffalo carcass was hanging. The lions couldn't get to it, as we had a chain link fence erected around the butchery, but the skinners tent was just outside the fence. One of the lions flopped down next to their tent, landing on one of the guy ropes, and collapsing the tent down on the three poor fellows inside. They sure had a wide awake night!
It did make the next morning's hunt awful easy, all we had to do was walk right from camp on their tracks.
