Flies are just annoying and yuck!!!! We had a cook out one year and you couldn't even get a piece of food to your mouth before a fly landed on it We all had to go inside just to keep from eating flies
I'll bet it was in the best weather, right? Just before the heat of summer hit I wanted to do patio dinners. For a week we did the same thing - brought the food inside. Little beasties. At least I have a big picture window. lol
