something wrong with having a native Hawaiian convention IN Hawaii?

The convention went where the Hawaiians are.

not really joking though
a LOT of my family moved away, including my grand babies
=======================================
HONOLULU (HawaiiNewsNow) - More Native Hawaiians live on the continental U.S. than in Hawaii.

And according to the US Census, more are leaving every day, largely because of the high cost of living.

That fact is why the Council on Native Hawaiian Advancement says it decided to hold its first convention ever outside of the islands. The inaugural Western Regional Native Hawaiian Convention is set for June in Last Vegas.

Makes sense.  Same thing that keeps other groups from coming to Hawaii -- travel, airfare, cost of hotels, rental cars and food, etc.  Can't exactly jump in the minivan and chip in for gas to get yourself to Hawaii.

When you want maximum attendance, you don't use for the most inconvenient and expensive venue/location.
