I am a scavenger. I prowl the alleys and streets hunting the stuff other people have thrown away.

Anyway, I've started marking the places where I've found decent things.

The marking has been done with found stuff as well. The extra-large push pins, the sticker sheets, and the printer (and ink) were all found in the last few months.

While the BPA logo would have looked better in color, I had only the black ink that was in the printer...as you can, perhaps, tell from the printed sheet, using the printer software to convert the image to grayscale didn't work (I could have converted it in Illustrator, but I didn't want to waste any more ink). Plus, you can see that, even with a printed circle, I can't follow a line to
cut things out.

Where to place the pins has been a question. I had no problem with sticking one in the side of a beat-up garage and another in a tree beside a dumpster, but I couldn't bring myself to put one into a freshly-painted fence. As for dumpsters with no easily stick-able things beside them, I've pressed the pins into asphalt (don't yet know what I'll have to do if there's only concrete around one).
