Stop the presses. Petaluma leaps into the forefront of eco-piety. Great idea if you’re a single person picking up the evening’s dinner, but if you’re a working mom who goes to the store once a week to feed three kids you’d better bring a whole bunch of cloth bags. BTW -the bags will have to be washed, mended and replaced when worn out. Good thing those working mom’s have so much extra time and money to tend to someting that used to be free.
