Interstate 40 bakersfield east

Funny story about I-40 by Flagstaff. One winter about noon my wife and I were driving East on I-40 and approaching Flagstaff and the snow started. My wife was freaking out saying we needed to get off the road so we did not get snowed in on the highway if it were to continue. We pulled off and got a room in Flag for the night and the next morning had to wait until the plows cleared about 10" of overnight snow from the roads so we could continue. We got back on I-40 and within a couple miles, the road started 'losing altitude' and within a couple more miles there was no evidence of snow at all! Had we driven 5 more minutes the day before we would have been totally out of the storm!
