The cavemen probably did not give a lot of thought to landscape drawings when they captured their surroundings on the walls of their apartments.
If I tell you that I don't give it a lot of thought, its just because I don't want to explain myself. I like the randomness of mountains and rocks, I like sahuaros and cacti because they are strange, I like birds because they can fly, and I like the Arizona sky because it is so infinite.
I saw one artist write about another artist: "he is ONLY a landscape painter." I wonder how you say "&@%$ off" in Caveman?
