George, have you tried calling Ellen Wilkinson, the USFRA lady of all duties? I don't have her phone number handy - do have it at home -- but if you email her at the USFRA website "contact us" button I know it goes to her. Also - MONTEUSFRA, here on this Forum, is one of the head honchos at WoS (and also the starter). Try asking him (with a PM).
Either Ellen of Monte might be able to steer you to a pre-entry that will cost less than buying one at the gate.
You're welcome.
