California is one of 12 states, plus over 500 communities in the US who been single use plastic bags. My experience is that California stores offer heavier, weight reusable plastic bags that they charge for at the registers. So I make a habit of keeping a stash of single use bags in my truck so that when I go to California and go to a store I carry those in to use. I do not like paying five or $.10 or more for a plastic or paper bag.
