The worst snow storm I ever had to drive in was in AZ. I nearly got stranded in Flagstaff during a blizzard and then almost wrapped my car around a telephone pole trying to get out of there before my car got buried in snow.

I imagine Monument Valley is extremely cold since there's nothing to stop the wind chill.

That whole region is pretty brutal, and Flagstaff in particular. There are days (and this can happen at any time of year) where the temperature difference between day and night can be as big as 50 degrees difference. When I was in Flagstaff last May this was the case. It had snowed overnight and it was 30 (let me re-emphasize that this was late May) but during the day it went up to 80. Not to mention that but it's in high altitude so the air is thinner, I had been in Boston and LA which are at sea level, and then Yuma/Imperial which is actually BELOW sea level in the days before, so the altitude change also was giving me breathing difficulties.

Having said all that, I still love Arizona to death, particularly Northern Arizona; but it should not be overlooked that it's a really harsh part of the country, element-wise; not for the faint of heart.

I've lived through some Arizona winters, I know how it can get. the freezing rain and frost are miserable.

Ahh, another nice image of one of my favorite rodents.

Muchas veces la imagen sobre un sitio nos muestra una cara diferente de la realidad. No sabía que nevara por Arizona :O

xD single digits cold?

Yep, I remember a couple of those nights when I lived in Flagstaff. WUnderground says we hit a minimum temperature of -6F, although I somehow remember -8F. Blizzards too, with snow so high you had to wade through it and icicles three feet long. Even during the day, if I rode my bike after getting out of the shower, my hair would freeze on my head. I faced the darkest nights of my depression in that snow, so I was often up around 3 AM when it would hit those temperatures. I remember thinking that if I just fell asleep in the cold, I wouldn't wake up to see the morning. Ironically, I never fell asleep myself (went so numb I would scald myself with water before I got feeling back though), but one night on one my late night wanderings I came across a drunk student who fell unconscious in the snow and so I called up Flagstaff PD to help him (he was unresponsive when I tried to wake him). He didn't seem happy when the ambulance finally arrived and revived him - but I was in no condition to come out and find him dead in the morning. I had a hard enough time living with myself back then.

Lots of snow though, and as I didn't have a car, I must say that I despised snow-plows for making the sidewalks unrideable (although after being left in a snow drift a giant chunk of ice effectively forced me to walk for the rest of one winter).

oh sorry now i get it,
i use Celsius since i live in the uk, water doesn't freeze until we hit 0 Celsius so the single digits are not really that cold
