Good luck in your quest. At this time of year that's a tall order to fill. I was able to attend #1 and #2 (but will unfortunately be absent this year). The only down side to attending this outstanding event is that most other beer fests in your future will pale miserably in comparison (In my low life opinion the only other 2 Fests that I have attended that even come close would be Brewvival and Charlotte Octoberfest ..... due to the great homebrew tentssss).

You could try asking the Raleigh Rare Beer fest twitter account. They were retweeting people asking them if anyone had extra tickets.
