Just Say NO!

Don't use them!  Plastic bags have been banned in San Francisco, and several cities are following their lead.  Use reusable grocery bags .  They're inexpensive, easy to find, and can carry a lot more weight than their plastic counterparts.  If this is not an option, opt for paper bags- although not ideal, they're still more environmentally friendly than plastic.  If you must use plastic, please recycle.  Walmart has plastic bag recycle bins at the doors of most locations, as do many other retailers.
