Hi - I'm new to roadtrip America, but looks like I will love it! My husband and I are planning a trip from North Carolina to Las Vegas, leaving on Friday of this week. We plan to take I-40 all the way and our first stop will be in Oklahoma City (Yikes! - the man wants to drive 16 - 18 hours the first day!!) I see his reasoning, in that we can drive from our home on day trips to see the sites as far as Nashville or even Oklahoma City. So, my question to you is: what are the most important sites along I-40 to be sure to see. Another question is - are there interesting places to eat along the way. Husband has been diagnosed with diabetes, taking insulin 3 times a day and I am worried that we may not have restaurants readily available. We are taking a breather after Okla City and so our next stop will be the Grand Canyon. On the way back, we plan to stop in Albequrque, NM. Any suggestions will be GREATLY appreciated.
