To answer your questions, a local Denver news channel did a vid story on this last night and the “group” camping out in the supermarket parking lot looks like a ragtag band of peripatetic meth heads, sorta like Deadheads but only with the meth part and no music, or a latter day group of Gypsies from the crackburbs of Detroit rather than mother-ship Romania.
Yeah, well the pitbull’s owner certainly has that look about her - that was my first thought when I saw her picture, anyway: “meth head”.
