Tunnel-tramplin: This project just started last year. The goal
of this tours is to walk exactly over a tunnel. That means exactly there,
where the line of the tunnel is drawn on the map. Until now we (Simon Scherrer and me) have been walked on the Swiss
railway-tunnels called Heitersberg and Hauenstein. |
