The corner of Alfonso Calderon Boulevard and Rolando Arjona is buzzing. Car horns are blaring and 18-wheelers are speeding in both directions. There are motorcycles -- lots of them -- and they are inching closer and closer to the sides of the vehicles that have come to a screeching halt at the traffic light. The thumping mix of Mexican banda music provides the soundtrack. The car next to Julio Urias' plays romantic music with the windows down at full blast.
