The little “W” icons and notes feel like an updated version of hobo signs, the glyphs used by drifters to share place-based knowledge in what passed for crowdsourcing during the late nineteenth and early twentieth centuries. Marked on walls and doors with chalk or coal, sometimes carved into trees, the signs warned of threats—zealous police, vicious dogs, bad water—or pointed out resources: safe campsite, kindhearted lady, work available.
