I did manage to score Castle Whiterock for $25 in the dealers room. The only defect leading to that price was that the front of the box was dished in about half an inch, and the lamination was thereby a bit lumpy. Finding the time to run this monster will be a real challenge, but at the very least I can dip into it for short scenarios for a long time to come, if not run a campaign of it.
Like an idiot, I didn't also grab the second copy that was there! (I'm sure someone here still needs a copy. Feel free to curse me to your dying breath.) I realized my mistake about 15 minutes after leaving the dealers room, went back in, and some other lucky gamer had already snapped it up.
Also picked up DCC16 and DCC25 for a total purchase price (with CW) of $36. I wept, I laughed, I required resuscitative magic....
Strangely, I didn't play any D&D (nor any sword & sorcery genre) the whole weekend...
