Yeah well anyway...gravel ends up getting shoved into the same end of the parking lot where the snow goes, leaving bare ground and mud. Then, it needs to be redistributed in the spring. It also provides an endless supply of rocks to be thrown by vandals. |

It also provides an endless supply of rocks to be thrown by vandals. The operator raises the blade of the plow so as not to scrape the gravel. It's not like plowing pavement where the blade must ride on the surface. A half inch or so of snow on gravel makes little difference to the traction. Are the vandals in your community prevented from vandalizing by paved lots? -- John H. "Divide each difficulty into as many parts as is feasible and necessary to resolve it." Rene Descartes |

Are the vandals in your community prevented from vandalizing by paved lots? Damn, you really should work on your comprehension. That question was just plain stupid. |
