Boulder scrap is rentals, alleys, and the occasional authorized cleanout

Boulder’s rental calendar dumps appliances and frames every year, often into alleys that were not designed for a large truck. Older houses in the same grid hide copper and brass behind plaster. Parking permits and alley widths decide the pickup more than the commodity price does.

Campus and lab surplus is a separate, documented process. If you cannot say who authorized the material to leave, do not send it. Household coins and jewelry go to the gold page. They are common in a university town and easy to lose in a scrap description.
