That's why it's called illegal dumping.

Officials with Greensboro/Guilford Crime Stoppers say items like mattresses were dumped illegally in the Old Battleground and Greystone Pointe area.

"It's like how many mattresses do people get rid of all the time," Elizabeth Thompson said. She lives in the Old Battleground area. "I mean every hour there's one up there I swear it's crazy."

The problem clearly hasn't gone unnoticed.

"It's a horrible problem," one resident said.

There are 'no dumping' signs all over Cotswold. 

"I see a lot of trash or you know furniture out at the side of the road and everything," another resident said."

Greensboro Police say illegal dumping can cost you thousands of dollars in fines, and potential jail time. Illegal dumping can be a felony in some cases.

The City of Greensboro says they'll pick up your big throwaway items like mattresses for free.

Just put your stuff at the curb on bulk collection day, which happens every other week on your regularly scheduled recycling day.

If you see illegal dumping in your area, report it to the GSO Collects app.
