Any high mountain passes through Montana/Idaho on I-90
Headed to South Dakota from Portland, OR along I-90, curious if there is any high mountain passes like on I-70 through Colorado?

If you've pulled Cabbage Hill on I-84 east of Pendleton, the grades and pulls on I-90 in ID and MT will be a piece of cake. The pass on the ID/MT border is the toughest but your Dodge should handle it with ease.
