Mr.McDonald is correct.  In my observations, the big blue carts in short order simply became an extra trash can for most folks.  A seemingly free extra 6-8 cubic feet of disposal every other week.  I am a supporter of recycling that makes economic and ecological sense, not just recycling to meet some pie in the sky government mandate or some "feel good" action.  The co-mingling was a pie in the sky action to meet government mandates for more tons of delivered recycles (not) and the plastic bag ban in Eugene was simply a "feel good" action.
