Need a little advice.. Leaving central California, heading to Dickinson, Nd. Trying to avoid climbing months if possible. Are the climbs through, SLC, and Wyoming Ok? Or should I add several hrs...
There is a grade on I80 from SLC to Evanston, WY. Is your plan to take I80 east to Cheyenne, then north? I'd be more concerned with cross winds west of Cheyenne. If you take I15 to Butte, Mt you will have some grades on I90.
Leaving SLC east on I80 I just take it slow. Use the right lane & flashers.
