This year in Michigan we are having a most unusual year of not much snow and higher than normal temps. I have over 1000' of gravel driveway and use PVC pipe on all of my straight edges (loader, blower and blade on Gator). With the snow-pack-thaw, rinse repeat year, I can't seem to keep the gravel off the lawn even with the PVC. Today with a rain imminent, I just used the blower to blow the snow banks back into the driveway for melting putting any gravel back on the drive. Beats raking in the spring.
