Our awning is supposed to reel itself in; if the wind becomes too strong.
The problem? We always get nervous, and retract it before it feels that the wind is a problem.
We figure that wind gusts can twist them up quickly, so we always keep a lookout for them.
Oh! One more thing...
We don't leave it open in the rain. We'd rather not risk putting it away wet, and growing our own crop of Penecillin.
