If the U.S. wins on Thursday, and so does Italy, then the U.S. goes to the second round of the World Cup (the U.S. could also advance with some other situations, but this is the simplest; the one thing for sure is the U.S. needs a win). If this happens, the U.S. will likely play on Tuesday at 10 a.m. Chicago time.
The question is, of course, do I skip YAPC to watch? The sessions during that time are Learning Perl 6 (sorry brian and Randal), Intro to Catalyst (sorry jibsheet), Catalyst-based software, Solstice Framework, web testing, web testing with Selenium, Module::Compile (sorry Ingy), and maintaining CPAN modules.
Suggestions are welcome, as are solicitations for companionship in front of a TV at a nearby pub, hotel lobby, etc.
And, of course, it's all moot if the U.S. doesn't advance.
