So I was looking at different cities using Google Maps and the elevation finding tool below, and I tried to find the residential housing unit(be it a house, condo, apt, etc) that is the highest above the lowest elevation of that metro area. Sea level places are the easiest obviously, but this is what I have come up with so far...if youre interested and look these up yourself and find any mistakes, please let me know.
