When I got back to the border there was at least a half mile queue 3 deep of foot traffic. I had a plane to cathch in LAX and couldn't afford a 3 hour wait. I was approached for a taxi ride to the border for 5$. I took up the offer and was put on a bus which travelled about 50 yards but got me through the border in just under an hour!

That line moves pretty quickly and you may have reached the border just as quickly (or possibly faster) on foot than in the bus. The $5 is usually not worth it.
