These have got to be engineers with too much time on their hands. Am I right? (Daughter and sister of engineers. My daughter roomed with an engineer for two years in college as well, and her boyfriend's brother is an engineer. We've known a lot of them.)
True story. We mentioned in passing to the daughter's roommate that we needed an alarm for flooding in the basement for when the septic tank was backing up. He instantly started designing a solution, spent real time on it. Turns out you can buy this alarm in Home Depot, $35.
And my reaction to the above was, they don't really get much snow. And the first guy's Forester goes through it, so why does he need to plow, just drive on it. At some point in the season, the banks of snow will be at window level along my drive, even with the guy bringing in the bobcat that has a huge blower on it every once in a while to move it back more. In a normal year, it's hip deep on the sides of the sidewalk by Christmas. We spend $1000-1500 on snow removal every year. Roughly 400 yards of drive, plus shared expenses for the road between our group of houses and the county road. The guy wouldn't even bother plowing that little amount of snow.
