In a city were most families do not have a car, street vendors play an important role.  The vendor calls out his wares as his burro slowly plods up and down the streets.

Some vendors make their daily rounds offering a variety of commercial produce.  Others sell their own harvests.  Many watermelons and cantaloupes are grown near Lerdo.

The kids love to play on the wagons.  Chico is good at imitating the calls of the vendors.

t is not unusual to see mama burro and Jr pulling a wagon, but it is unusual to see a battery-powered loudspeaker on the wagon.

Some stores offer home delivery. A few use motorbikes, but most use a bicycle or tricycle.

Sometimes the vendors come on foot going from door to door like this man who was selling very colorful bedspreads.

The ice cream vendor is always a welcome sight. 

The corn-on-the-cob (elote) is so good with lots of spicy butter or mayo or Mexican cream.

Some vendors set up on the same spot every day like this taco stand by the number 2 park.  Note the shoe shine stand in the background.

Some set up in front of their homes in the evening or on weekends like this lady who makes pollo al carbon.  I drive by here often on the weekends, and it always smells so enticing

Update 2012, 10 years later,  The burro-drawn wagons are mostly a thing of the past, replaced by pickups.  Door-to-door produce vendors are much less common because of the spectacular increase in car ownership (and attendant parking problems) that allow a greater access to grocery stores and markets..
