As always, there are lessons to be learned, although no one ever seems to. In all the recent incidents, I am struck by one thing that was consistent. The hikers had no food or water and only the light clothing they were wearing.

Whenever I go on a hike, even an easy trail that I've done many times like Aiea Loop, I take at the minimum a liter of water, some snacks that vary from granola bars to Spam musubi to PB&J sandwiches, a poncho and extra pair of socks. Also, I bring my cellphone and a small flashlight. I also always have a pocketknife and a lighter with me unless I'm in the shower. That's my bare minimum. Geeky? Yes. But try spending a night outside with any less.

Another lesson learned, from this case in particular, is to stay on the trail and while others may disagree, I say "do not trust a GPS". It is a poor substitute for map, compass and orienteering skills. Search and rescue people will tell you horror stories about people following a GPS to their disaster.

A standing rule is to always leave a hike plan -- destination, route and expected time of return -- with a responsible person. Adding to this, I recommend a simple check of the weather report. Lastly, consider your physical condition. Be honest with yourself. There have already been a couple of cases this year where a hunter and a hiker had heart attacks out on the trail.

Being safe isn't dorky. It's a lot more fun than having to be identified by next of kin.
