I absolutely loved reading this book and I don't even use the tube that often, being an out and out country bumpkin. It's humorous, informative and down right eyebrow-raising in equal measure. David Long obviously knows his subject and has captured the tube, it's foibles and its fancies perfectly. I would strongly recommend this book not only for anyone who uses the tube on a daily basis but to anyone who has any interest in this great and important part of London and its history. It's perfect for tourists, but is intelligent and deep enough for even the most battle-hardened commuter to learn something new from. You never know, it might actually make the journey more bearable with its useful hints and tips on tube etiquette and optimal seating arrangements (just small examples of what this book has to offer). I actually want to go back to London and do an 'underground' tour with this book acting as my guide!
