Throughout the first five years of Miller Park, I kept track of several events.  
During 2001 this includes a running record of Miller Park firsts, month-by-month
record as compared to an open or closed roof, month-by-month attendance,
daily home run count for each team, and a list of teams, in order, to visit Miller
Park.

This can be viewed at on the old site until it is converted to the new format.
