Yeah, they only way to get to Vegas for APA singles is to win a spot.
The L.A. area has no qualifier? That would be very surprising. I think if you check out the
national site, there is information available to show you how to host a qualifier. Basically, you'd need like 4 people to make a small board, I think, then the top person would go to regionals. From there, all of the people that made their qualifier would play in their brackets. If you have, say, 24 people in a bracket, I think, then the top 2 would go to Vegas. The brackets are broken up into..
For 8b: 2/3, 4, 5, 6/7
For 9b: 1/2/3, 4/5, 6/7/8/9
This next year, 6s will have their own bracket in 8b. Last I saw, the 6/7 bracket is freakin big.
I also checked the national site to see who all was qualified so far. I see players from Northridge and San Diego, but nothing from L.A., so I'm thinking that the regional must be recent so they don't have that info yet. It's hard to believe that they don't have one at all.
You can still drive out and play in the mini tournaments if you want, but that's a long 5 hour drive for some minis.
