A friend of mine was telling me that driving East on I-40 into Flagstaff is a long and steep drive. That I will be down to 35 mph at times. I was also told the same about Grants Pass in I-5 going into...
As others indicated....no problem. I would not call it steep. It's a long slow incline. The difference between Flagstaff and Grants Pass area is that you're at a higher elevation. Flagstaff is nearly 7000 feet.
