'I-Spy' books have apparently returned to our bookshelves (now sponsored by Michelin) and seem to be offering a wealth of additional extra dimensions to the avid 'spotter'.
In my day, my ABC consisted of locomotives and the like.
Has the hobby really degenerated to spotting railway carriage lavatories ?
UPDATE: This from Sussex Driver....
Is there a category for working toilets?
Surely this would be worth bonus points!
