I can remember working during some serious blizzards back when I was a cop in Michigan in the mid-late 1970's. Several times it was so bad with wind and lake-effect snowfall that the highway was closed for several days between parts of Michigan and Indiana headed to/from Chicago until the winds died down and the road crews could clear the highways. One time that took 3 days. I remember those blizzards being 1977 and 1978 if my memory hasn't failed me (again).
Several nights I was assigned with another officer to just block the west-bound lane at one of our exit ramps and run a line of about 20 flares to warn oncoming traffic that the highway was shut down because snow drifts 3 to 5 feet deep made the highway impassable. Other departments along the highway were doing the same thing so there was very little traffic but once in awhile some vehicle would get on the highway as there were just not enough officers and cars to block every entrance. We would direct them to get off at our exit and try to get back home or to a local hotel until the blizzard subsided.
One officer would run a line of flares and then come back to the car to get warm while the other officer would do the next replacement flares, which burned out quickly in the high winds. You would take turns running the flare line then getting warm for the entire shift. 50+ mph winds and near 0F temps will chill you to the bone in a hurry if you are standing out in the open for any length of time. Our dept had officers with their own 4WD vehicles and they used them to answer complaint calls and to deliver boxes and boxes of flares to the officers blocking the highway. The exit ramp we were blocking had a truck stop so we could walk up there for bathroom breaks and to get some hot coffee.
I actually enjoyed this type of assignment.....to a point. It was a break from dealing with the local criminal element (of which there were A LOT) in my area. At the end of the shift, another freshly fueled car with two oncoming shift officers would replace you and you could return to the station to gas your car and try to get home. Luckily, the guys with 4WD would take you home since a regular car would probably not make it unless you lived really close to the station. In my case they would drop me off at the nearest intersection (about 1/8 mile from my house) as my road was totally impassable with snow drifts well over waist deep and I would have to walk the rest of the way. Next night they would pick me up at the same intersection for my shift..... wash/rinse/repeat until the roads were re-opened.
Ah, at least I was in my mid-20's and recently out of the Marines which made it 'easier' to be out in that type of weather. I am 68 now and although I am really glad to have experienced Michigan blizzards during most of my life, I now in South Carolina where winters are much milder!
