Brandon will be a Guest of Honor at ConQuesT 46 in Kansas City on Memorial Day weekend. Although I haven't seen an announcement on his site, the con has Brandon's schedule here. (And here's the full schedule for those who are curious.)
EDIT: Brandon's announcement of his schedule.
Will there be any 17th Sharders there besides me? I'm not sure what I plan to ask Brandon, but I'm open to sufficiently interesting suggestions.
Also, I've never been to a con before. This one only caught my interest because it's close and both Brandon and GRRM will be there. For those who have attended cons, what suggestions would you give to a "con newbie" to help me best enjoy the experience?
