I incident meter everything (color and BW). It's not like slide film, you've got plenty of latitude especially if you're scanning the negatives. You can adjust the colors so much you don't remember what you started with too. For that reason, a DSLR reference shot with a manually selected white balance is a nice reference to have, even though it does not have the style of LF qualities or big dynamic range you are after.
Where you headed in Maine? Most of my photos are in Maine. Feel free to search my photostream for things like Portra
https://www.flickr.com/photos/13759696@N02/ A LF photographer who did color well in Maine was Eliot Porter, but you wouldn't know he did it well unless you see a first edition of one his books (sometimes found at libraries) or the dye transfer prints he was known for. I think his kodachrome style can be replicated by taming the contrast of Ektar in or post scanning, or slightly boosting the saturation of Portra once scanned.
