I just looked on the ground of my car, got the dust out of my stash jar, and scavenged stems :|. I got a good sized bowl out of it.
I have several strategically placed emergency stashes. I place them so that if I'm ever out for a long period of time I won't find them all in one day, I hide each of them in progressively more secretive spots so that I eventually will find them all, therefore making them last longer. But usually I just get more weed.
