The Blue River runs the length of Silverthorne, willows crowding both banks and anglers standing in the current most months of the year. Lawns that back onto that water keep their own habits — damp in the low corners, quick to green, quick to go rank — and Hood Landscaping Inc mows, trims and edges to suit them. Along the riverside paths the line between mown grass and wild willow is worth keeping crisp, and it takes a steady hand to hold it. Spring and fall cleanups take out the drift of needles and leaves the current will not carry off. Good grass beside good water is a fair thing to work for.
