I did. Today is primary day in Pennsylvania (and perhaps some other states as well).
I voted at 9:05 am after dropping my daughter off at school. I was voter #13 in my precinct. According to Allegheny County, there are 648 registered voters in my precinct (as of the 2006 general election). Polls opened at 6 am. You do the math.
Chances are you didn't vote. See Chris Briem's analysis here.
