Zoo found another winner today. After discovering we had 35 miles of construction between us and Salt Lake City, he chose a road north that connected with the arm of the salt flats we wanted to hit. Below are images from just before we left paved road, to an unmapped (by Google) dirt road, Nevada to Utah to Nevada to Utah and then back onto the highway again and into the city limits of Salt Lake City.
Zoo almost stepped on a Horny Toad! (LOL..)
