Here's a view we had of Oahu's second-largest "heiau", Ulupo, in 2003. This is located 2 blocks from where my family lived in Kailua and was allegedly built in one night by the Menehunes.
Ulupo has a dedicated group of volunteers taking care of it and they are inviting one and all to a celebration.
