Along the US-Mexican border, specifically dense areas like Tijuana, Mexican vendors sell their food like fruit melanged with Tajin spice to people crossing the border via carts. In recent years, these food carts have been threatened by tightened border security at the Port of Entry. Both the US and the Mexican governments have proposed a project that would widen the streets of the border, allowing for more people to pass through the border. Widening the border would decimate neighboring mercados that rely on the business of travelers.
