Actually, the text message that went awry came out a few minutes past eight, and at that time I was at home in Kaneohe getting ready for the hike, which was supposed to begin at 9 a.m. at the end of Ala Aolani Street. I'll admit that I was a bit alarmed upon seeing the text (see below) but when the expected civil defense warning sirens never came (at least not where I live), I figured it was a false alarm or a hoax. It turns out that if was the former.
In any case, the hike was on and I headed to Moanalua Valley where I met Steve, who was oblivious to all the chaos. We did see some hikers beating a hasty retreat out of the valley and upon questioning them, they said they were military types who were ordered back to base as a result of the missile-threat-that-never-was.
As for the hike of Bay Bum Ridge (Steve said it might be a play on Bay Rum Ridge, which if so, still would warrant a how and/or why explanation about the naming), we hiked up the valley road until reaching the fourth bridge. At that point, a trail heads up on the left thru a bamboo grove (trailhead pic below).
Bay Bum eventually intersects the north/left ridge of Moanalua Valley at a prominent Norfolk (or Cook Island?) pine grove. Starting at the end of Ala Aolani, speed hikers can likely reach this grove via Bay Bum in an hour, but Steve and I were not in speed-hiking mode on this day (plus we're old--me, 59, and Steve, 70). Thus we took a more pedestrian, botanical pace (Steve loves to talk about flora along the trail, including the healthy koa tree pictured below).
From the pine grove, we headed down (makai) the north ridge, following a well-cleared trail and enjoying ample views, including one of the Waianae range in the distance (below).
