Ahhh, another fellow South African :) As youngsters on a school trip we went to the Drakensberg and jumped into the icy rivers once. It knocked your breath away, some got nosebleeds, lol. So yeah, I can only imagine how cold it must have been there.
Thanks for the earlier support! If you'd like you should come and connect with us on Discord (fellow Saffa's-Team South Africa): https://discord.gg/9V3ug8
