I am new to the forum and congratulations for the website and discussion. It is very helpful!
I tried to spend some time searching it before posting. Sorry if my query was already addressed and somehow I missed that.
My wife and I are planning a road trip from Chicago to Los Angeles this August on a Mustang convertible. The initial idea was to broadly follow I-40 westbound but we have a concern about the heat especially when crossing Texas, New Mexico and Arizona. Do you think this might be a concern, especially if we plan to stop a bit on the way?
Alternatively we were thinking of driving on I-80 (and I-70), perhaps chiller in August, but we are not sure which one has more sightseeings. What was a priority for us was stop at Grand Canyon and Las Vegas and we can do that on either of the itineraries. We know that each of them has its beauties but with only 13 days to cover Chicago - LAX one way we think we need to chose one of the two itineraries... or perhaps there is a third alterative route that would look more interesting for a first timer on US inter states?
Many thanks for your advice or any road experience between these two cities.
