996, in Yosemite Valley, you are (I am sure) right. Also, there are bear boxes -- no need to hang 'em up, and campground bears are like Yogi -- smarter than the average bear.
But I still have not heard a good alternative to the hanging method when you are boondocked for several days far from campgrounds and dumpsters. And folks who are more experienced than I am still use the hanging method. So I am going to stick to that device, only when it is absolutely necessary, until someone comes up with a better system.
