If you live in oklahoma you should go to this: http://www.freeok.org/
only $10
And....oklahoma...you need more outspoken freethinkers...why are 2 texans headlining your convention? ;)
Anyway, congrats to oklahoma for starting a convention. I already have plans for this year but will go next year if it is organized again. Every state should have a grassroots affordable convention like this...I'll help anyone wanting to start one get things moving.
