Hey Summer,
No booth (not this year, anyway). I'll be wandering around with a microphone and headset recording folks most of the weekend, except for Friday when I'll be in the judging for the commercial meads.
As far as an SCA presence, those of us there constitute it, I guess. No official SCA presence will be there that I'm aware of.
I'll be looking forward to the commercial braggot! Does your friend plan on having a tasting table at the Tastings?
