Stickers and Stamps Update 10/23/2020

The more I learn about the US Postal System, the more I'm amazed by it.  Every address in the US has a "Sectional Center" that all mail going to and from that address passes through.

A sectional center facility routes mail between local post offices and to and from network distribution centers (NDCs), which form the backbone of the network. -wikipedia 

For the envelopes I mailed in the US, I've annotated my data with the USPS sectional center that the letter passes through before it reaches it's destination. 

I haven't figured out what happens with international mail, yet. But the current research focus of this project is to figure out travel times within the US. 

In this set of map-sketches, I'm looking at how far an address is from it's sectional center and how long a letter has taken to arrive at it's destination. The grey circles represent the sectional centers my letters have passed through. The lines radiating out from them represent an individual envelope's journey from that center to it's destination. If a line is teal, it traveled from San Francisco to it's destination in a few days. The more orange lines indicate that it took much longer to be delivered. I'm still working on the color scale, so I'm not sharing a legend yet.

To preserve privacy, I'm using the lat-lon of the town or city as a destination's location.
