at some point in the mid 2000s, i started taking pictures of darkclouds signs and stickers and mapping them on flickr. once i ran out of space in my free account, i stopped. my photo collection on flickr focuses on the boston area. even after i'd stopped actively looking for them, i'd still catch them once in a while. the photos above are a handful i took in manhattan and burlington (vt). my flickr images (including the map) are here.
