Author Natalie Ogbourne is visiting the Knoxville Public Library tonight.

Ogbourne will be speaking about her book “Waking up in the Wilderness: A Yellowstone Journey.” Ogbourne is an expert on Yellowstone National Park and she has traveled 60,000 miles there -and-back from her home, and has visited there almost every year since 1981. Her newly released book shares lessons from the Yellowstone trail. The event starts at 6:00 pm and is open to the public.
