It's been so long, that I've forgotten what impulse led me to choose this topic. If I try and think about it now, behind the fence might be this magical space you can only see parts of. Which makes it even more interesting if you can't cross the fence and usually heartily disappointing if you do manage to enter the other side. Behind fences lie private mysteries not important enough to lock away in dark cellars...or nothing at all. Depends which side you're standing on.
