Keith Howard used to be a homeless drunk veteran. He now calls a six by 12-foot converted motorcycle trailer home. He used to be a drunk. He’s now been sober for 11 years. He used to be toothless. He now has a mouthful of teeth. He used to be a veteran. He still is. Howard maintains tinywhitebox.com, his website, helps out at Hope for New Hampshire Recovery in Manchester and tries to rouse the rabble.
