from the Oahu Trailblazer guidebook....."Old timers will say 'Ewa' to mean 'West' and 'Diamond Head' for 'East,'regardless of whether you happen to be east or west of these places. On all the islands, left and right are avoided in directions. People instead say 'mauka,' meaning turn inland or toward the mountains; and 'makai' to turn toward the coast. Nowadays, McDonalds' is used frequently, as in, "take Vineyard Avenue to the McDonalds, turn right, go two McDonalds, and make a left." If all the McDonalds on Oahu were on the coast (thankfully they are not) you could grab a Big Mac every two miles.
