Up until 10 yrs ago, Mine was gravel too and i would just leave some snow on it, I usually leave the snow until its done if it looks like we will finish with showers or drizzle, But we had 0.85" of rain after 6" of snow so it was not going to matter this time around, I was kind of hoping the clippper tomorrow would have helped with 1-2" but that looks to stay north of here now.
