OP is correct. Although the original letter DID say that tickets were going to be required to attend this year's annual meeting at the local AH or KH, a revised letter came out this week saying that the GB changed their mind and that tickets will no longer be required. So I guess any of us could crash the meeting and see what the big deal is.
Honestly, I think that it's going to be just as underwhelming as all the other 'special' events they hold, although it may prove to be a useful cure for someone with insomnia.
