A camp road off Pawtuckaway Lake tells you the entire year in one stretch of gravel: mud in April, dust and green shade in July, a white trench between banks by January. Bz services of N.H LLC works roads like that around Nottingham in both directions on the calendar — mowing, trimming, edging, mulching and cleanups while the ground is open, plowing, shoveling and sanding once it closes. The lake makes its own weather, so storms tend to land wet and heavy on this side of town. Clearing a drive down to gravel in winter and then coming back in June to cut the same yard is a good way to learn a place. Either job ends the same way: something that looks looked-after.
