Said waterway is paradise compared to where you go on holiday.
See an offal rendering plant, processing the guts, gizzards and various off-cuts from the seediest butchers in the most economically-challenged village on earth?
See the huge iron cauldrons used to boil such slop, the bits of animal bowel, mucous, chicken toenails and cartilage adhering to the rim as the contents are poured from there into an acid bath?
Do you see that steaming, gritty, foul pot emitting such a potent stench that not even the bravest of flies dares to draw near?
That's your prime holiday spot, that is. That's where you curl up with your copy of 'Inside MS DOS' to read on vacation.
