I know we live in MN and the weather is very unpredictable. This weekend is my wedding and it has been staying around the upper 80's. Now its saying 92 and partly cloudy. Our ceremony is outside and is only about 20-25 mins tops. Does anyone have any idea of anything we could have to keep people cool. Everyone is in direct sunlight. I was thinking maybe some umbrellas but then that would block peoples vews. TIA!!!
