We will be arriving in Vegas on 7 Oct just a few days prior to our arranged vacation rental in Vegas starting on the 11th. We want to rent a car and start driving the morning of arrival to Alburquerque N.M. to see their balloon festival - I believe its a little over 8 hr drive. I am concerned that at that time of year, it would probably be dark before we get to Alburquerque. Is this a difficult drive - one that should not be done in the dark, and are there any weather conditions possible that time of year. We would take Highway 40 most of the way through Arizona and into New Mexico.
