Don't despair Stumpy, the permit you want might materialize.  I have often found they become available again as other reservations are re-arranged, cancelled, etc.  At one time I thought I was told there is a particular day of the week (month?) that the cancelled reservation dates get put back into the available system.  Has the difficulty alluded to on another thread been cleared up?  I'm going to take my chances and wait till closer to BWR time to work out a permit.
