Precisely. I live near Yosemite National Park, and it would be an absolute disaster if there were enough hotels, campgrounds, and amenities to meet the demand. The demand FAR exceeds its capacity for tourists, but it would destroy the very reason for that demand if that actually happened.
So what did they do? Set rules for the number of tourists allowed in the park per day, and stuck to it.
Hmm. It's odd that this isn't ALWAYS vibrating, but it IS only between these two poles that I've noticed the vibration. But why not between other sets of poles? And since the cable vibrating the most isn't a power cable (I believe it's fiber, but it could be copper - but it's definitely telecom, since it's not insulated on the top crossbar, as the other power cables are), it can't really be much power going through it. I'm kind of hoping someone else has seen similar behavior somewhere else. You can see the anti-wind-twist devices (don't know what else to call them) bolted to the other telecom cable (sort of diamond-shaped) and they will cause the cable to stabilize when the wind is really blowing, but you can see the wind isn't blowing at all, and the cable continues to vibrate quite noticeably. I really do hope someone else has seen something like it elsewhere...
