One of the shrines in LA has this weird allusion to something named Pankoa:

Place itself looks like ruins of Utopian city, but i don't get the reference, neither google does. Any ideas?

In the list of backers, there's a

"JEREMY BETTY CHIACHEW PANKOA"

entry.

Kickstarter rewards for $1000+ pledge include following:
BECOME AN NPC, WEAPON, OR LOCATION in the Wasteland 2 world! We will get your name and (if relevant) a picture of you to add your general likeness to the actual shipped game.
for $5000+: We will BUILD A STATUE, in your honor.

So yeah, that may be the case. Too bad credits do not disclosure those additions by authors.
