Yeah, I mainly describe things or if I want some aid, I'll use a picture or a briefly drawn map. I like doing that because it allows the PCs imaginations run free and they come up with ideas that you might not have had with a physical representation. That and am an OSR, back when you didn't have minitures...just a book of rules, paper, pencil, dice, and imagination was all you needed.
As for the writer block thread, I'll probably start tinkering with that again in the next month or two...unless something else pops up beforehand.
