Definitely agree with you about the tombstone types of things when dealing with comics. I've read a few to get voices right for characters that aren't in the MCU, but man, there are so many comics with so many different representations, and I have no idea where they all fit in a line because timelines are a thing that don't exist in the Marvelverse.

Google Maps is a savior, you're completely right about that. I have connections to the National Geospatial Intelligence Agency and have sent my acquaintance emails about maps and satellite imaging before (luckily, this person knows me well and isn't alarmed when I also bring up things about hiding bodies, though never in the same email). And all of that makes me think of this great Tumblr post (http://freaoscanlin.tumblr.com/post/53765651076/zyea-shrineart-seananmcguire) I saw floating around the internet last week.
