What is art?

A friend and I went to the Northrup King building last week. Here is a picture of the building above. It is recognizable from a distance because it has this water tank on top that totally reminds me of that old television show, "Petticoat Junction." The building has art studios inside and on the first Thursday of every month, the public is welcome to walk around and look inside the studios. We saw watercolors, oil, acrylics, sculptures, jewelry, mosaic, and weaving. The artists are in the studios as you walk around. Sometimes it gets a little awkward. We walked into one studio where three people were listening to a guy sing all the words to Steve Martin's song, "King Tut." My friend told them, "Carry on." and they did eventually. The building had signs posted saying "Minnesota Nudes III." We thought we'd go look at it. We entered a very large room. Photo prints were on the walls and there were 7 older men in the room who quit talking when we entered. We had at least 50 nudes to look at. All the nudes were young women with ideal bodies. One series had two lovers in the photos and both were young females with ideal bodies. The seven older men were the photographers. None of them spoke the entire time we were in there. Evidently there is an annual contest. Seven photographers are chosen and only some of their prints are displayed. Most of the portraits were outside. Some women were laying against rocks. Some were posed with half of their bodies in fast moving streams. One was a woman in a deciduous forest with her arms up and I thought she looked like Jane waiting for Tarzan to swing by and pick her up. Several photos, in my opinion, crossed the line into pornography. My friend and I didn't say a word while we were in there. We both agreed there was a creepy atmosphere in that room. We took a look at some abstract art to cleanse our eyes before leaving.
