I have noticed that there are almost no tournaments in Washington. People will say "Set one up yourself.". I don't have the money right now to do that. Heck I only have a zero g stadium. So if anyone can set up a tournament in Washington thank you.
Well, the answer to your question is indeed that you and others in your region have not taken the initiative to host anything there. That is the only reason. It does not really require much money at all, seeing as we usually manage with barely any prizes, so, as you mentioned, it is indeed just a matter of acquiring legal stadiums. However, they are basically required for any serious collection anyway, so more than one person in your local community should make the investment for their personal gaming.
If you want to get something set up, you should post in one of the topics dedicated to Washington in the WBO Beyblade Communities - North America forum.
Bro, I needed tourneys here for years. If You got any ideas pm me.
