You know very little about the true history of the Ewa Plain. It is far richer and has one of the most important cultural histories of Oahu.
.
Kanehili Cultural Hui and especially Kepa Maly have done many volumes on the real history that few people know about- and that's why the HART Rail project wants people to believe what you are saying is true. 
.
Also the Navy BRAC (Barbers Point - Kalaeloa) in 1997-99 by the Tuggles, highly respected archaeologists, revealed the extensive cultural histories and large native population in Ewa Honouliuli that HART and SHPD want to see wiped out. 
.
One of the major volumes is "The Synthesis of the Ewa Plain", a very well researched and documented study which is intentionally kept confidential by the US Navy so that the public, especially Hawaiians, don't ever know the real cultural story of Oahu.
