should I sue?

a lawsuit in most cases is a no win situation. The comp. at the end isn't worth the headache of the suit. Now, I do agree that as a member of the town you should get the pop. to introduce a discussion with a log kept, with their m.o.p. to act on the situation at hand. Some of us do live in places where we get snow and sometimes it's better to stay home when we do.
At the end of the day if they hire more, everyone pays more!

good luck.
