What's right with this picture?

Is this an example of something bad about a school or no? I think it looks awesome, because portables were lame enough, and at least these kids get a nice open-air learning environment, even if it's in a gym. Aside from losing the use of the gymnasium for soccer baseball, what's wrong with this picture?

And who doesn't like the feeling of walking into a school gym... Communists?

On another note, I try way too hard to disagree with everything I read at the Globe and Mail website.
