Just because we do not follow a certain activity does not mean that those who do are "sad". The fact that Stobart lorries are always immaculately clean, and that they are named, makes them easy to differentiate one from another, just like railway locomotives. Train spotting has been a hobby for as long as I can remember and, while I never took an interest in it, I don't regard those who do as "sad". I'm sure there are many people who regard we boat modellers as sad, too, but we know better, don't we?
Having said that, I realise that there are always those who will go to extremes, even to the extent of risking their own, and other's, lives, and this is deplorable. However, it doesn't mean that all enthusiasts should be tarred with the same brush.
