You know if there's one thing i've learned from University it is that analogies never hold up....there's too many variables......i mean, how clear is the map, does it resemble another area? what is the knowledge of the person using the map? do you assume they even know how to read one? I thought that one post i saw in particular about plecos was harsh, and shot down the person, in a manner i know they were previously shot down in....history repeats
