I might actually be in Milwaukee that day - 4th August will be the 50th anniversary of my first-ever live baseball match, and if things work out I might catch the Nats on the road that day.
[also re thread title - Orioles-Mariners is 2nd/3rd/4th August, Friday/Saturday/Sunday - Monday 5th is currently open (or are you betting it's going to rain on the 2nd/3rd?)]
