You have a Mars Blvd., Jupiter Ln., Uranus Ave., Canal St. all near by in one neighborhood. I can't tell from Map Quest, but there is a Mars HI reference in there as well; that could be Mars Hill. That's about as connected to Percival Lowell as you can get.
BTW, while the Lowell Observatory discovered Pluto, it was not Lowell that did it, but Tombaugh, after Lowell died. I would discount Pluto.
This makes me wonder WHY these streets were named this way. Frequently "developments" are named after relatives of the developers. Certainly they are often named by the developers. The "pet fantasies" or hobbies of developers can get involved here, at times. Any ideas of these origins of names? Any connections that I haven't seen with other clues?
There is also a Mars Drive? I will look through that. Update: Mars Dr. has less "connecting" feel than the Mars Blvd. It also is much further away from the river and where the two parishes come together.
Still connecting dots?
