Woodbury in late March is mud and meltwater and a lawn that looks like it lost an argument. The Dirty Nerd Services starts right there — spring cleanup, winter's wreckage raked out of the beds, the grass opened back up to light — and then holds the line with mowing, trimming and edging straight through to leaf season. Up on the hillside properties the ground falls away fast, and cutting them well takes patience more than horsepower. The reward is the middle of June, when the whole yard finally looks like it is on purpose. Woodbury and the towns next door.
