A $10 day

I've mentioned before that one of my favorite perks about working at MIT is occasional parking.  I can park 12 times a month for $5 a day which is a bargain if you know anything about Boston/Cambridge parking.  I wasn't very good about keeping track this month (until Thursday) and I overshot my 12 times.  I used to keep track of my period; now I keep track of my parking.
