Well... temporally halfway. Writing-wise, not so much.
I think I passed a major psychological hurdle yesterday, though. This whole site/scene/challenge thing is going to make it a lot easier for me than I thought it would be.
Also, I decided against mapping everything out. That takes a load off. Do you need a map for the manor house in Greenstone? Why? I don't plan a fight there. I don't expect the PCs to search through it like a dungeon. A map would just encourage that sort of behavior. I'll give a description of the place. That should be sufficient.
I may, after the month is over, toss together some extra maps or something for download... bonus material for the adventure. I'm not going to worry about that now, though.
