Traffic School or Not?

Allstate says 1 point on your record doesn't change your insurance.  2 points and the good driver discount goes away.  Points stay on your record for 3 years.  They always recommend going to traffic school so that it stays off your record, but then of course if you get another one in 18 months you can't go again.

I think I'll roll the dice and skip the school this time.  If I get another ticket in the next 3 years, then I go.
