I had two lucid dreams last night-- my first lucid experiences in a month! I even completed one of my two dream tasks: I found a payphone and asked a dream character on the other end if he knew anything about my communal dream location. Unfortunately, he didn't, but we did have a nice chat and visited a carnival. With pirates!
The second task, of course, is to try to re-find the desert city while lucid.
It seems like we have quite a few people who're interested in this idea. How great! If anyone has any progress or visits any more strange, foreign-feeling locations, post and keep us updated.
