There is also a thriving reverse traffic for those seeking entertainment in Tijuana, or purchasing services (vehicle repairs, hair and beauty services, childcare, medical and dental) that are generally more affordable there.

For this reason many cross on foot, the line for which is frequently much faster than the vehicle line. Some foot travelers own a car in each country, and store them in one of the large parking lots located near the border post, or use the respective public transportation systems of both cities (both systems have a bus station built solely to serve the border crossing point, and the San Diego Trolley
