The blacktop market is an underground economy, outside of the fierce taxation of the Authority.
Trade is most often improvised when there are no Spy Scouts or CrowBot troopers visible, or when traffic is especially slow. Some regular goods that are often traded include: homemade food, weapons, caltrops, doombrew, counterfeit CrowBucks, narcotics, candy, furnace goblins, clothes, and pets. While bartering is the most common medium of transaction, small bottles of poison is often used as a blacktop market currency.
