It is going to be about 58-60 the saturday of my wedding as predicted so far. I am having an outdoor ceremony and reception in an old barn that due to fire code can not have open flame or heaters in it and any heat source has to be at least 50 feet away. Should I set up a tent in and place the heater at the far end so it is 50 feet away but will heat the entire tent so that older guests will be comfortable and other guests will have a place to warm up if needed or do you think everyone will be fine?
