There are only 2 more qualifiers left before the final play off. See the CALENDAR for exact dates.
Maybe DanMayo will see this thread and may be able to answer your questions better than I can. However, I don't think anyone from this site has played in their event since it is primarily aimed at locals, but I could be wrong. On a different thread he (DanMayo) made the following statement:
The "Scarey" Eagle is just the text I put onto the link. The nickname comes from them having some of the worst Blackjack conditions in the state. But the closest competition is a couple hours away so they don't care and get a lot of ploppies anyway.
As for distance from Detroit - about 125 to 175 miles.
Seems to me that anyone coming in by air should think twice. To actually win a WSOB seat would require 2 trips - one to qualify and one for the play-off. This makes for a substantial commitment in time and money. Also, Indian casinos are not known for giving breaks on room rates. The tournaments are on a Saturday - Friday and Saturday being the most expensive room rates of the week.
