We've used Abbots for the last two years for one-shots and they are great. As weekenders, we arrive late on a Friday. I just tell them when I'm showing up, and the driveway is clear. I've even had them do a second plow over the weekend with just a phone call, or panicked waive at the end of my driveway.
Last winter was a ridiculously light snow year. We could easily have four times the amount of snow next year. Just in the last 7 years I've seen berms on the sides of the roads nearly 8 feet tall. The first winter I came up here we got 6 feet of snow in 4 days.
