Hi, I'm new to the site and need your help! My husband and I are taking a road trip from OKC to Los Angeles in a few weeks, and we're planning on using I-40.

I suffer from motion sickness, and what gives me the most trouble is driving on twisty, windy roads. I also know that when I went to Colorado about 10 years ago, I got altitude sickness for the first few days of the trip.

Can anyone who has traveled this route before tell me about the conditions of I-40 going through the mountains of NM and AZ? Are there plenty of places to stop along the way, if I do get sick? If it gets rough in places, would I-10 be a good alternate route?

What is this route like, in general? Are there any 'must see' places along the way?

Thanks for the help!
Monica
