I guess it comes down to a glass half full/half empty approach; why did they decide to have this sale? Personally, I was very surprised by it, given both the recent history of memberships, and the historical lack of Black Friday sales on tickets for the following summer (at least the past 5 years or so, that's as far back as I go). I guess, for me, that surprise tends me towards the glass half empty approach.
One other note: the fun cards do not have any black out dates (aside from expiring Sep 8).
