March is the month that actually snows in Commerce City — not the dry powder of January but wet, dense, heavy stuff, a foot of it dropped in an afternoon that bends the elms and buries a parking lot to the curb stops. TQF Concrete & Snow Removal LLC plows through those days out where the warehouse country runs east toward Tower Road and E-470 and the wind has a clean run at everything. Big flat lots are their own discipline: long straight passes, piles stacked where they won't block a lane, entries opened wide enough for a truck to swing. Getting it done before first shift is the entire point, and there's something plainly good about a lot that's black and clear at six in the morning after a night like that. Ice gets treated too, because in this town the melt and the refreeze both happen the same day.
