for garage sailing the poorer or older the neighborhood the better it is for computers, scrap. i've hit several in the last month along my normal scrap pickups that i first ask i they have any old computers, then say, I buy them for metal salvage. 90% of the people make the connection and their next question is, so you take scrap metal? sometimes, but only when it's offered. <--- instant confediance that you're not there to rip them off. i find rich neighborhoods are better for freebies, mostly calls on my craigslist ad, they just want to recycle and curbside service won't pick it up.
