Stuck in traffic

Next time you are in a traffic jam, think about these guys. During Semana Santa (Holy Week) thousands of tourists, both Mexican and foreign, descend on Oaxaca. Traffic is terrible, as I imagine most Mexican people drive here, plus more taxis than usual were in El Centro area servicing the people without cars. 
These men have probably hauled this wooden furniture from where it is made - at least a mile (uphill all the way), and who knows how far they are going. It's possible they are vendors, and people can buy a bed frame or book case or whatever they happen to have with them. There was nothing for them to do but wait, holding their heavy loads.
