I got mildly interested in flag design after watching videos like this...
... and this.
Anyway, the North American Vexillological Association (people who study flag design) voted Pocatello Idaho as the worst city flag in the country. To be fair, it was truly terrible.
A few years ago, Pocatello took that judgement to heart, and finally decided to redesign their flag. This is their new flag, which is lovely.
Anyway, I'm saying all this to show you a design that they considered, but ultimately dropped in favor of the red mountain above.
I think this flag design is so cool and unique, and just deserves to see the light of day. It fits perfectly because Pocatello is the "crossroads of the west". This diagonal cross hatch design just makes me happy, and I kind of wish it had been chosen. Maybe something similar can make it onto another official flag someday.
