How long will blue bags last?

With rubbish collections due tomorrow in this area, I see that, quite apart from the ‘no more black bags’ message having not got through, the ‘only two blue bags per week’ message still hasn’t got through to many households either: there are some with over twice that number put out for collection… regularly. And as the dustmen, whilst refusing to collect black bags, seem to quite contentedly collect any number of blue bags, I reckon that some people will soon be running out. At which point, they’ll revert to using black bags… which won’t be collected. Swindon in the spring is going to look so pretty….
