No. You can Uber there, if you have copper wire or pipe. Just request they send a vehicle with enough space to fit the amount you have in that vehicle or taxi or a friends car or truck. The scrap yard will weigh the metal, or in your case "copper" in baskets. They are quite good at St Pete Scrap Metal.
