I found this on the net and paused because it is interesting so I thought I would share it here for Halloween 2014.
In Mexico, just a few minutes outside the city of Oaxaca, one can find the Old Panteon Viejo and New Panteon Nuevo cemeteries of Xoxo (pronounced ho-ho), which were originally established by Spanish missionaries in the 16th century. Xoxo is the local name for the Xoxocotlan village.
These cemeteries take on a macabre vibrancy on Halloween night (31 October) in preparation for Día de Muertos (Day of the Dead) celebrations. To welcome the spirits of lost loved ones believed to return on November 1 (All Saints Day) and 2 (All Souls Day), villagers decorate the graves with bright orange cempasuchitl (Mexican marigolds), candles, figurines and food. Around these festive gravesites, family members gather to wait for the dead while drinking mezcal (an alcoholic drink other than tequila made from the agave plant), eating favorite foods and listening to mariachis (Mexican folk music).
