Some people are children of the sun. They look better--even smell better--the hotter it gets. In 100-degree heat, you couldn't wipe the smiles off their faces with the gross hanky you use to mop your perspiring forehead.
But there are enough of us non-children of the sun that on weekends we clog every traffic artery leading to any place marginally less searing than the Treasure Valley. For that demographic, there's the Ketchum Arts Festival. Enjoy food, live music, more than 100 booths and exhibits of arts and crafts and a Kid's Activity Tent offering free childcare. And don't forget refreshing breezes and cool mountain air.
