Koko seems correct....and least from my experience. Riding at dusk is one of my favs during the summer months. MT, ID, WA, OR, UT, WY, MI...makes no difference, I deer & elk x the roads. BUT, was riding toward St. Mary's (East Entrance Glacier National Park) and a COW bolted out from the trees. Whewwwwww, my lady, I, and the B almost bought it. All I saw was something massive and black out of the corner of my eye - and thought it was a bear. lol
Almost hit a Horse riding on the reservation in Monument Valley.
