Hi! I shall be visiting the US this April from overseas, and I'm considering a road trip between Las Vegas and Houston. All the mapping websites can give me directions and a route map (travelling I-40 for the largest part of the journey), however, I don't know where to start planning visiting attractions, choosing places to stay, or even whether there's anything interesting on the way! I'm giving myself about 3-4 days for the trip, but what next?
Can anyone nudge me in the right direction? Is this a trip worthwhile? And do I need to plan the good old fashioned way - check out every town/city enroute and take it from there?
