I40 or I70 west from Zion, NP to NC

Not sure how far East you are planning to go on I-70 before heading South. The past few years it has been pretty rough through Indiana. We prefer I-64 from Saint Louis East. It is better road and not as much traffic.

Right now, today 10/12....there is the first major storm system of the season moving into California tomorrow.
High winds and lots of rain are expected.

Fast forward to the weekend, and CO should get a major weather event.....

FYI only.....

I just used I=40 from Gallup to just south of Nashville and half of the rest areas were closed. In one long construction/one lane there was NO construction going on but here was a asphalt plant set up. Other than AR the rough areas were fairly short and there were not any serious delays in the construction zones... probably a half dozen of them... a mile of one lane for bridge work is not counted and there were 3-4 of those. Been several years since I've used 70 so no comment other than the best way to see Kansas is at night or from 30000'.

you might find damage from Matthew, when you get back to NC
