October out by West Woods and Long Lake is the best fortnight Arvada gets — cottonwood gold, blue sky, air with an edge on it. GreenSpace Landscaping spends those days on rakes and blowers, pulling leaves off lawns before the first storm mats them down. The rest of the year is mowing, edging, trimming, core aeration, overseeding and fertilization, run on a cycle so nothing gets away. A yard cleared in autumn comes back faster in April; that is most of the trick. It is satisfying work to look back at.
