A few weeks ago, I covered a local Ganesh festival. Which can be explained here: but long story short, lots of parades and good food and sending Ganesha back to heaven by being sunk in water. Also, while researching this on wikipedia I came across this little tidbit that I thought was interesting.
“Today, the Ganesh Festival is not only a popular festival, it has become a very critical and important economic activity for Mumbai, Hyderabad, Vishakhapatnam, Bangalore and Chennai. Many artists, industries, and businesses survive on this mega-event. Ganesh Festival also provides a stage for budding artists to present their art to the public.”
