I thought the ones with big numbers were the mile markers.... the others course markers.... they formed a nice ^ to drive into and all the markers made it easy to pick out the spot on the mountain to drive to. While we always try to make it between the markers, the reference on the mountain tells you that you will go through. Most of us rarely use the lines on the highway close to the vehicle to stay in our lane... we look down the road. That works well for LSR.
The little cars never see the lines till they cross them...

Try it, see ya on the salt
