Ugggggh, if you win at the qualifiers, you still have to compete at St. Louis? They should at least have made St. Louis invite only to be more fair to the other 6 tourny areas. Now, it seems that Philadelphia is going to be the most popular location (with New York, Washington D.C., Boston, Chicago, and Canada being nearby) I'm assuming that there will be about 2000 people who sign up for seniors (there's no quiz?). That gives you about a 1/32 chance to even get in. Also, you have to be in the top 4 to guarantee yourself a spot at nationals.
As for Worlds, there are only 60 (30 per age group) competitors. That's less than last year.
