As you all know, Friday night's Orioles vs. Yankees game at the Camden Yards was postponed due to the nasty, incelement weather outside. There's not been a makeup date announced as of yet, and fans are advised to hold onto their tickets.
I have not heard or read anything on exchanges or other arrangements to handle the ticketing for Friday's game. I found that quite unusual.
Also, fans who do not have tickets for Saturday and are looking purchase them from the box office may want to read this from the Communications Department of the Baltimore Orioles...
From Birdland Insider: Fans coming to Sat night's game are advised to purchase tix in advance or arrive early to avoid long wait times. Big walkup expected.
In other words, buy your tickets early -- either at the box office, online at orioles.com or places like Stubhub and Tickets Now. Avoid the lines. It's painful and I can speak from experience.
