I've been "driving" around on GoogleMaps in the Cambridge Apartments. The pins you get when you enter an address in the interior of the complex are not in the correct spots on Google. I can't see all the addresses posted on the buildings "driving" around, because the Google car did not drive into the streets in the apartment complex very much.
What I figured out, though, is that 5301 is very likely right next door to 5303, as the building continues into the complex. The numbers on building 5313 (just north of the parking lot of 5301) go up by twos as the Google car turns into that street of the complex (5317, 5321 and 5323 are visible). They also go up by twos on 5295-5299, south of 5301. The Google pins for the interior numbers (5317, 5321 and 5323) all end up in the big middle of 85th, not even close to where they actually are. The pin for 5301 is correct, as it is on the end and right on 85th Ave. The pin for 5303 also ends up in the big middle of 85th (a "generic" pin, if you will), because it is an interior building, not viewed by the Google car.
The numbers on building 5301 very likely increase by 2 as they extend into the complex as do the others, only there is no side street to drive in on to see. There is only a sidewalk. 5301 is the outside building on 85th Avenue in its string. The next one in would be 5303. Tenants would use the same parking area. Same short sidewalk going to park. Same pool. Etc. These two addresses are not 348 feet apart. They are right next to each other.
Whatever anybody wants to make of that....I know what I think.
