New municipal trash regulations make it mandatory to cover trash put at the curbside for pick-up by council crews.
That is, you have to cover your trash unless you live on the growing list of streets that have bitched and moaned such that the weak-kneed council has granted an exemption to your street.
But in the meantime, the regulations require trash be placed in polyethylene bags of a minimum thickness of 1.5 mils.
Consumer trash bags - bin liners to U.K readers - typically come in a maximum thickness of 1.2 mils. That's the really heavy duty expensive ones. Most bags are under 1.0 mils.
Don't take my word for it. Look at glad.com and check the faq on trash bags.
There are 1.5 mil bags out there. Just don't think you'll get away cheaply. Bags to meet the regulations are available online and will cost between US$30 and US$50 per box depending on how many bags come in the box.
Count on this regulation being repealed pretty quickly.
