There is something about London’s Underground system, The Tube, that appeals to me. It seems more secretive than “normal” railways, sneaking around out of sight most of the time.
The news that there is now a London Underground and Tube Tour [^] gives me something to add to the must-do list for the next trip to UK. Now, how do I convince Mrs CannibalRabbit that she wants to spend 2 hours underground after spending a day flying half-way around the world?
