Just thought I'd point that out, if the developers are reading this, and are making an expansion or second edition.

I'll be marking the locations and lead pieces with a sharpie, to fix my copy.

We used post-it flags to differentiate locations for one of our color blind friends.

I am thinking of using some kind of white pen and write a number 1-5 on the different type of locations.

Had to ask my 3 year old to help with set-up. Don't think he realized the reason Daddy asked him to differentiate the "bwue" and "puwple" physical evidence leads was because I couldn't tell the difference!
