Rob Piltz (rrp@cs.arizona.edu) has this to say:
"While aluminum siding requires little maintenance after it has been installed, I still prefer the look of natural cedar shake siding. It may be more work, but I think that overall you will be pleased with it, you can stain it any color you like. Plus, your spleen will like it better. Natural wood feels more comfortable to your spleen than hard, cold aluminum. A comfortable spleen is a happy spleen."
