I don't know how I didn't think of this. I was just wondering if there was a way to filter Craigslist down to just local (<2 mile radius), but street-free works perfectly.
I've lived places that weren't dense enough for it to work. But in a fairly urban environment, provided that the item is not total crap, it tends to go fast. I have had cases where I found a taker after I left my front door to take the item out but before I had set it on the sidewalk. :D
