Rivalries between suburbs in the same metro area

[Pete from Boston]

North Shore vs South Shore here, but primarily if you're in high school actually or mentally.  More so it's inner vs. outer suburbs, urban vs. suburban suburbs.

It's more of a sports rivalry than anything, but Pearl and Brandon are rivals. To a lesser extent, Madison and Ridgeland. To be honest, it's usually the suburbs vs. Jackson.
