Borders in the developing world are places where informal and formal spaces converge. This has been recognized in recent years among tourism scholars, but the role of the suppliers (i.e. vendors in this case) as informal tourists has until now never been examined. Formal tourists are enumerated, taxed, inspected, and issued visas, while informal tourists are not. Instead, they travel back and forth virtually unnoticed across international boundaries with products to sell or trade, but in most cases they are relegated outside the formal tourism system.
