It's been running for the last two days. Since the last storm, it dried up and then came back during a clear blue sky. My host family tells me that the drainage is enormous, that the water is coming from Vryburg (about 200 km away in Northwest province). Whatever the reason, I love it. I walked in the drainage on my weekly visit to Laxey even though it probably doubled my trip time and had me scrambling in the brambles and thorn bushes. Something about water, especially muddy water, makes me happy.
