Something seems out of whack here.
If Minneapolis "can mobilize 100 plowing vehicles" to plow "3200
lane miles", that works out to 32 miles to plow per vehicle. Now from my
observation, those plows have to go fairly slow, especially in alleys, etc.
-- I'd estimate that they average 8-12 miles per hour. So that means about
3-4 hours to completely plow the entire city, including all alleys,
etc. (And in less than half a work day, so no overtime pay required to do
it.)
Now I know this does not take into account the time required for
issuing a snow emergency, time for people to move their vehicles, time to
call in the drivers of those "100 plowing vehicles", and time required to
drive them from their garages to the streets that they have to plow. But
it still seems like the city is taking longer than needed here. The
current plan takes 72 hours to accomplish what seems to be, from Sara's
information, about 3-4 hours of actual plowing. What are they doing the
rest of that time?
