Sweet Jumping Jimminy, this is quite a project you've taken yourself too, I am duly impressed. I'm glad you're using a program like CC to do it, otherwise I can't even imagine how much work it would be.

I had a very similar inclination to do something like this after I bought the Expedition to Undermountain book, then wisely said "That's crazy".

You're maps are very good, and even more importantly, useful! Repped all the way.
