The Big Thompson runs past Milliken under old cottonwoods, and the town's yards keep a stubborn green all summer while the surrounding fields cycle through corn and hay. Boulder Bros Landscaping LLC keeps them cut — weekly mowing, trimming around trees and posts, edges held along drives and walks, clippings cleared away. Weld County mornings in July are the good ones: cool, still, sprinklers just off, the grass standing up ready. A yard cut into clean parallel bands is a small thing that changes a whole street. Homes and business grounds in Milliken and out toward Johnstown, Mead and Berthoud come around every week.
