All are lovely, but the Ground Level Plan is my fave. Seeing these reminds me that I spent years writing a traveller adventure (it's now up to page 60 or something) and made the fatal mistake of putting it down and starting something else, so I never quite finished it. I must go back to it. LOL! I remember now, I put it to one side because I had some maps to draw for it and I wanted to improve my mapping. That was about 5 years ago.
