I knew the games in Pittsburgh would sell out but I didn't think it would happen in February! Luckily for me as a Sox fan in Pittsburgh, Cleveland is only a 2 hour drive and the Sox are there in April and May.
Palodios has got it; since the Sox go to Camden Yards every year, there is not the same demand as in Pittsburgh. I have been living in Pittsburgh since 2006 and have been waiting (not so) patiently for the arrival of the Sox!
