Not much in way of details: it was fall, night, they (her friend) saw it cross the road. Both positive of what they saw.
Both also, as with all the stories I've personally heard from individuals, familiar with Oregon wildlife, and used to the outdoors. Camping, hunting, living in rural areas; they know what things are. And they know when something out of the ordinary looms up in front of their faces.
As always with stories like these, I have to wonder at the knee jerk reaction from debunkers and "skeptics." This woman was not lying. All the other people I've known, who have told me their stories, were not lying. They are also a diverse group of people in terms of age, profession, gender, etc. What they have in common is a familiarity of the local outdoors, and a love of the outdoors, and damn well know an elk from a bear from a coyote from a cougar. (One witness's Bigfoot sighting was such a profound experience this person continues to look for Bigfoot many years later.)
