A`ole pilikia (no problems).  I do not post comments to ridicule or call people names (most of the time, anyways).  I just believe we ALL need to recognize the changing climate of these islands.  I believe most malihini like yourself come to the islands to live because of the natural beauty and the lifestyle.  If we want to preserve it we need to  do the simple things like learn street and place names (and words like "mahalo").  Otherwise we will lose it completely.   You seem like a cool person so I don't think you are malicious or anything like that.  As far as the name Kaukonahua and what it means.  I think it could mean "a fruitful place on the leeward side of O`ahu".  I think when the road may have been put in it was put in to make what was once a pineapple and sugarcane community Wahiawa, Waialua and Haleiwa accessible before the new Kamehameha highway was put in.  Since I am not from that area I am just assuming the meaning.  Best to talk to some Kupuna/elders from there. Aloha.
