A February storm over Bloomington usually shows on the radar hours before anybody hears it on the roof. SRT Services keeps that watch and rolls when the accumulation starts rather than after it stops — plowing drives and lots, opening sidewalks and entryways, salting so a dawn refreeze doesn't undo the whole night. Prairie snow is a moving target, sliding back across an exposed approach nearly as fast as the blade clears it, so some properties get seen twice before morning. The ambition is small and very specific: somebody steps outside at seven o'clock and simply leaves. Getting that right, storm after storm, is the entire work.
