Once. I was called to a historic courthouse in Gettysburg, PA even though I no longer lived in that County. I was excited about it...I actually WANTED to serve because law has always interested me. I wanted to be a lawyer and even sat in on some law classes at Gettysburg College when I was about 13 or 14. Then, I considered the 6 years of school and massive debt, and went into Accounting instead.
I wore a tie and tried to get on...I was one of the first dismissed while rednecks literally covered in oil from working on cars before coming in were selected.
I guess I looked like I knew too much.
