I put in for leave the day the schedule was announced last Fall. My boss already knows that OD is a religious holiday in the Church of Baseball, and knows that if I don't get my religious leave approved, I'll come down with a severe case of Red Seam Fever that day. I'll get there early and spend all day soaking it up - haven't missed an OD yet.
The first sip of the first beer of the first day of the season - ahhhhhhhh.
I'll do my traditional Find a spot to Park at Vienna Metro early. Take Orange line to Ballston and go to the IHop for a good breakfast and read the paper. Get back on the train and get to the park by the time gates open. Take in the store. By a program. See if anyone else I know is there.
