Betsy and I took the kids for a walk at Ludington State Park this morning. While hiking, we noticed a large tree that looked like it was billowing smoke from its trunk. To our amazement, it was just steam. As we continued walking, we saw several trees steaming. Eventually, the forest was filled with steam and sunlight. F4.5 at 1/40, ISO 100, 18-50 mm lens at 30 mm
