I wear glasses, so I hope they don't fog up too badly from the mist effects. I have to shield my glasses on Universal's ET ride in its misty segments due to it being blasted at full force at guests. Same could happen with the mist projection that was used in Pirates if I let the vapor hit them. The calm layers of mist used in the fort bombardment scene doesn't cause any issues however. Seems to happen worse when it's more turbulent and thick right around the head. Makes me a bit concerned with these new fog effects since they look like they might be both thick and turbulent.
