Tunnel vision

I love the sound of my bike tyres on tarmac as I whizz through tunnels. Sounds almost like a fighter jet swooping past. Almost.

A lunchtime meeting today allowed me to cut loose from the office and get on the bike. Albeit only for 15 minutes either way after I found this shortcut!

No roads for me. Practically. I love Edinburgh's cycle network. But I have never been through this tunnel before. Strangely.
