A new AFOL convention called BrickMagic is on its way! May 7th - 9th at the North Raleigh Hilton in Raleigh, NC. Check out the website http://www.brickmagic.org for more details -- there's lots of neat things including having Nathan Sawaya doing a live build over the weekend!
As for castle, there are some neat things already planned, but we still need more! So come on out and join the fun at the first AFOL convention to hit North Carolina, presented by Joe Meno & BrickJournal.
Sandy Cash (i.e. the guy who built Brickistan -- winner of BrickFair's best in show & best castle) has volunteered to be the castle coordinator, so I'll let him chime in with organizing the rest, but I wanted to get the ball rollling... it's only a month away!
Register now and start building~!
