Just as Simen says, no wind.
This is a campmaster tent that was a bit in the way of the elements at Bloemhof dam. Philip's sleeping bag was rinsed out of the tent as well as a white towl (only a loving wife would pack a white towl on a fishing trip) amongst other things. The towl enced up a nice shakey colour :-D
At least all the tent parts were still there. We were up in the Vetrivier waiting the storm out before we could head back because that strip of water can become seriously ugly in a storm...
Another such an experience was at Jozini. The tents ended up looking like a squatters camp as we had to fix it up each night we got back. We left just as management was going to complain about the rags we camped with :-D
I hate bloody tents ;-D
Oh yes, Billy, also at Bloemhof, thought his beer box was loaded enough to keep his tent anchored. He ended up running after ithat dome tent through the camp site as the wind rolled it through there, trying to catch it. It was really funny. Lesson learned - bring more beer (and tie the tent down ;-)
