So, lots of cities have gridded streets or streets with logical naming (First street, Second street, etc)
DC has a couple of pretty interesting street organization features though. First up: Quadrants! DC has 4 quadrants, Northwest, Northeast, Southeast, Southwest
the dividing line for the quadrants is a "crosshair" placed directly over the capitol building
every street in DC has a suffix indicating the quadrant. Instead of "1st St", there's "1st St NW"

Also! The streets radiate in both directions from the quadrant dividing streets (the dividing streets are named North Capitol, East Capitol, and South Capitol. There's no West Capitol because of the national mall directly west of the capitol building)
So, heading north, you hit A street, then B street, etc
Heading south, you hit A, then, B, then so on in that direction
Same with numbers going east/west.
