"There were actually two sets of arrows-one for Westbound and one farther South for the Eastbound. I figure this was to absolutely avoid planes going opposite directions colliding."

"Is that the one about 50 yards from the tracks,on the East side of Tooele? You can drive down a frontage road and get within about 40 feet of it,an easy walk."

"There's one on the south side of I-80,just a couple of miles east of Reno. It's on a stone ridge overlooking the Truckee River,and overlooks what appears to be some warehouses by 80. It's actually across the river from Mogul. Not sure anymore if the roads to it are still open,but the way I got there was from the western end of Riverfront Dr.;there's a road that crosses a little creek then goes north,then straight west for a couple hundred feet,then you go south and run alongside a creek about 1600 feet or so,where you'll find a road that goes north. That road goes to the right for about 200 feet,then makes a broad curve to the left. It'll take you right to the arrow,which was looking rough when I was there,but looks better (?) now on Google Satellite. Best to scope it out on Google Maps/Satellite before you go,it'll give you a better idea how to reach the arrow BTW-there's another one around Lockwood  and one farther east, north of 80,and I THINK there's one on the hill somewhere behind the Pilot Truck Stop in Fernley,but I haven't been to these yet."
