Look at the gas holder in this picture: http://i44.tinypic.com/2mx4z5t.jpg and what is the impression you get of it? Also, would it be something you would be happy to get a view of from your backyard and/or bedroom window everyday?
“Look, Ma! I made it! Top of the world!”
Now that I know what a gas holder is I’d probably be more nervous about getting vaporized than anything else. I don’t know that I’d otherwise care one way or another about having it in my view from home, however. Stuff has a way of becoming invisible over time.
