question about staking a power awning

I was wondering the same thing when I camped at the beach a couple of weeks ago. I saw some tied down and some rolled in most of the time. We rolled ours in most of the time because we did not have anything to tie it down. I watched a tied down power awning take one heck of a beating during a thunderstorm with 50-60 mph winds and the awning looked fine after the storm. I think I would have rolled ours in for the storm but the next time I go to the beach I will tie our power awning down so we can use it more.
