Erik Roner has BASE jumped and ski-BASE jumped all over the world. In Behind The Line Season 4 Episode 8, Roner ski-BASE jumps in Macedonia – a place where no ski-BASE has ever before been recorded. As it turns out, TGR’s Macedonia guide, Nano, is a BASE jumper. However, he’s never ski-BASE jumped before. Reversing roles, Roner teaches Nano how to ski-BASE jump, sending it off a huge cliff.
