Stop before you throw anything else away, and make sure you're not breaking the law while disposing of anything. This list has 6 things you legally can't throw away.
A co-worker of mine has an issue, and he didn't cause it. He lives in a neighborhood where two houses have 11 cars and one motorbike parked in their driveways and on the street right in front of his house. I think there should be an ordinance that protects a homeowner from another homeowner's excessive number of parked vehicles.
