I lived next to some urban woodlands and it was chock full of old garbage. Pull rings and bottle caps were pretty common. General construction debris was common: a couple of old bricks, roofing slates, wrought iron fencing that was nearly rusted out of existence. Once I found the case to a portable record player with a 1920s manufacture date.
