SCBWI Oregon has opened weekend-only spots for their Oct. 16-19 retreat. (In other words, for Oct. 18 and 19, which means you could still hit Western Washington's kickoff on Oct. 16 and book down to Oregon for even more fun.) For those who can only come Saturday & Sunday, the SCBWI member cost is $250. That gets you all meals on Saturday, a shared room Saturday night, breakfast on Sunday, and retreat sessions both days.
The registration deadline is September 30th. Check it out.
