See there is a race coming up at Sondela. I have camped at Serendipity not far from Nylstroom. More of a 4X4 or motor bike game farm. As for locking up bicycle. I have traveled Zimbabwe, Mozambique, Malawi and places in South Africa and most times land up locking bike to tree and sleeping with my tent door right next to it. Have also tied fishing line to it and me. So can get an alarm my bike is leaving.
