It is not the snowfall that gets people in Arvada, it is the third day: sun on the south side, shade on the north, and a walk that thaws at noon and locks up again by four. Ice Tree Service LLC works that refreeze. Driveways plowed, steps and sidewalks shoveled down to the surface, ice melt laid on the stretches that never see sun, and a return pass when a chinook turns yesterday's melt to glass. Getting a north-facing walk truly clear takes stubbornness. Somebody carrying groceries in February never has to know how much.
