I was looking over the details of the Taos Toolbox, a two-week master class in science fiction and fantasy being taught July 8th through July 21st. This year's instructors are Connie Willis and Walter Jon Williams, with a special guest appearance by George R.R. Martin.
This workshop looks like a blast, and I know from experience that Connie is an awesome teacher. Accomodation is at the posh-looking Snowbear Inn in the Taos ski valley, complete with nearby trout stream and the Sangre de Cristo Mountains.
I wish I had the dough for it, but $2400 is out of my price range this year, and there's no scholarships available. It looks like the Milford style of critique, where students are writing and critiquing fresh stuff rather than older, more polished pieces, and includes one on one sessions with the instructors. It looks like too much fun for words to me.
