Entrance to Preston Brook tunnel - copyright: @ Graham Horn - Geograph
We have been through this tunnel three times, twice going north and once coming south. It has one way working which works well if every body has the time??? It was working through this tunnel where I lost one of the navigation lights.
When going through tunnels if it is my bad driving or the drunken direction of the tunnel which causes the boat to ver to walls the side of the tunnel. (The tunnels are often not straight and also you can get hypnotised by it all?)
