Snow plowing contract

[Chris Snyder]

So whats everyones best practice for snow plow contract during winter months?

I use to do it by storm but thinking on going on seasonal contract but my main question is what if snow fall is limited and only get 1-2 snow packs a season and you paid for $X for season has anyone put a clause in there must plow minimum of 10 times etc etc Let me know your thoughts
