Subject: [PATCH] Update examples to reflect real US cities

Proposal:
Update example to validate City length between 1-50.

Reasoning:
For lazy developers like me, I started using this package by copying the examples for the addresses because I figured that they were grounded in real-world, common validation rules. I did tweak the State and Zipcode validation to be more general, but then we hit a snag when we realized that Novi, MI (4 characters) is a real US city. This led me to look into the real boundaries and I've landed on this PR as an enhancement to save headaches for other future lazy developers. :)
