Loved this guy's rucksack.
Liked how it was gaping open just a bit. Mine does that all the while, and you don't realise until it has worked itself open fully and all your stuff falls out.
It's a real problem. Think I'll call it "back sack crack syndrome".
Or is that name taken ?
Someone should write a history of the rise of the rucksack from humble camping essential to universal carry all.
