Wife's cousin called. Said they were at Yosemite and looking for a route to the Grand Canyon. They have a Ram 2500 and pulling and Airstream-guessing between 26-30 feet.
99 to 58 to I15. 93 is a good road, then I40. They can visit Hoover Dam but a new bridge bypasses the dam - 911 changed a lot of things. BK may have been referring to snow possibilities. But if going from Vegas to N Rim then another route would be better.
