What is art?

Yes there are some things I just don't understand. Today I photographed a towns Artist Studio Tour. Individual artists open their studios the public for the day, and the public can purchase maps with the artists locations and a brief description of each artists work on them. Then the map holders are free to spend a few hours travelling around visiting the studios. I met many intersting artists, who work to create real intellectual art and celebrate the beauty of the human form or nature, or even just have fun with color and design. It was a wonderful way to spend the day and I had a great time felt fabulous about the whole thing until my last stop. Tell me is this art? Are there redeeming qualities here?
