My son and I are planning to do a road trip from Los Angeles, CA to Springdale, Arkansas later this month. I have never driven this far east before from the west coast. Anybody done this before? I did a MapQuest on the trip and its 1584 miles and 23 hours of driving time. It routes me through I40 east through Arizona, New Mexico, Texas, Oklahoma and finally Arkansas. Springdale is in the northwest corner of Arkansas. We are budgeting 3 days to make this trip. I see this having to stop and rest twice overnight along the way - perhaps first stop in Flagstaff, AZ and second on Amarillo, TX. Some people are saying it can be done with one overnight stop in the middle like Albuquerque, NM and driving 10+ hours a day. What's realistic for this roadtrip with two drivers? How is I40 like this time of the year? Any interesting sites to see along the way? Any feedback would be appreciated. Thank you
