Doom,
I attempted to post a reply to Jason Overstreet's post...not sure if it will make it past the mod.
To paraphrase my post...I asked for further clarification of USBC's official position. While the USBC OC is a "member only" event, ANY individual can become a member simply by purchasing a membership on the spot. In addition, the USBC Masters and Queens are "member only" events, yet are still approved by the WTBA...and yet again, a membership can be purchased on the spot.
While it appears that there official response is okay, it does seem lacking in many ways.
