I go for a regular early morning walk around my local area, and over time have found over $20 in loose change, mainly around bus stops. Unfortunately our public transport has gone to a cashless tap on-tap off system, so loose change has almost dried up.
My best find was a pair of new black wedge shoes with a 5 inch heel which was left on a street corner, and found early one Sunday morning. No doubt some young thing was finding it too difficult to walk home from the nightclub in the heels, so ditched them. My lucky find, alas a size and a half too small. I can squeeze into them, but I end up with painful feet.
