There are plenty of dumbasses who get themselves into situations that they shouldn't have. My biggest beef is the numerous occurrences every year of people who hike partially up Half Dome in Yosemite, CA, decide that they can't make it and then use their cell phones to summon help via helicopter... With how poor our country has become, I've always wondered why SAR had always been "free"....
Funny you mention Half Dome -- I got to witness exactly what you're talking about there.
I've hiked to the top of that phenomenal rock 6 times now, and it still is amazing. On one of my recent trips, I was heading up the switchback trail just below the cables, and came around a corner to see a family of 4 sitting in the trail. The parents were anxiously asking everyone who came past them (me included) to give them water and gatorade for their approximately 15 year old daughter. Seems they had brought very little with them, and used it up quite early in the hike. The daughter was not doing well, and apparently suffering from heat exhaustion. Not only was this family (parents in their late 40's or so, 15 y/o daughter and 12 y/o son) completely unprepared for the hike, they'd had the daughter pass out the day before from heat exhaustion, too! Unbelievable.
Now, for those of you who haven't been on this hike, it's 8.2 miles from the trailhead to the top, with another mile or so to the parking lot. This makes for a delightful 17 to 18 mile round trip, with an elevation gain of about 5,000 feet. Where these folks were was about 7 miles into the hike, after an elevation gain of about 4,000 feet. It was summer, so temperatures were in the 80's, and the hike is mostly exposed. I take five quarts of water with me, and drink most of it on the hike.
I don't enjoy carrying a heavy day pack, but I make sure to carry what I need. I had plenty of water and food, but didn't feel like provisioning a bunch of people who didn't bother to bring what they needed, should have known better, and expected someone else to pack things for them. Had circumstances been different, and this a genuine emergency, I would have helped in a heartbeat. However, this situation was just plain stupid.
Our group continued on, and soon reached the summit. As we were soaking in the amazing views, we started hearing chop-chop-chop and sure enough, here came the chopper up the valley below us. We watched it move on up to the saddle below where the unprepared family was, land, and shortly after take off again.
I didn't actually watch them load the girl, but it's a pretty safe bet that the family used the 911 taxi to save them from their lack of proper planning. :thumbdn::grumpy:
