I did an art show this weekend that was in a covered pavilion.. it's a horse arena, so it had a gravel/dirt floor, much like kitty litter, but the wind seemed be funneled through the bard and never got much over the mid 40's... I don't do cold well and think I nearly froze all day Saturday.... Sunday was better, but still nippy... I sure missed the 100 degrees we had in June and July.... Even my wife was cold and she was born and raised just south of Chicago in central Illinois.
